Tectonic Significance Of Topographic Lineament Analysis Using Artificial Illumination: Offshore Southwestern Taiwan, Jinder Chow, Tzun-Der Lai, Char-Shine Liu, Robert Sun
Tectonic Significance Of Topographic Lineament Analysis Using Artificial Illumination: Offshore Southwestern Taiwan, Jinder Chow, Tzun-Der Lai, Char-Shine Liu, Robert Sun
Journal of Marine Science and Technology
A digital topographic relief map, shaded by means of artificial illumination, has been compiled for southwestern Taiwan for a lineament analysis of the area. We discover a pronounced fanning toward the southwest in the lineaments. Six major offsets of lineaments have been identified, with the following trends: N60°E, N60°E, N65°E, N85°E, and N40°W. The trends of the offsets can all be correlated with faults predicted by experimental models of right-lateral strikeslip deformation. This paper presents a detailed submarine topographic lineament analysis in southwestern Taiwan and provides additional evidence of Lu's model for the vast offshore area.

Assessment And Restoration Of A Neighborhood Wetland Invaded By Exotic Plant Species, Ryan Neal, Kimberly R. Payne, Lorena Moreno, Graham Duffy, Jonathan Peck, Mary C. Savin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The University of Arkansas Crop, Soil, and Environmental Sciences (CSES) Club adopted a local wetland in the spring of 2002 through the Fayetteville Parks and Recreation Department. This project has allowed students to interact with local community and governmental organizations as well as other academic departments within the university. Students have gained valuable laboratory and field experience through characterizing hydric soils, identifying bird and plant species, and analyzing water quality, soil nutrients, and microbial biomass. Under the main goal of restoring the wetland, the club has outlined both short and long-term objectives including soil and water assessments; removal of two …
Areal Distribution And Bulk Rock Density Variations Of The Welded İncesu Ignimbrite, Central Anatolia, Turkey, Ulrike Mues-Schumcher, Rolf Schumacher, Lothar Georg Viereck-Götte, Petra Lepetit
Areal Distribution And Bulk Rock Density Variations Of The Welded İncesu Ignimbrite, Central Anatolia, Turkey, Ulrike Mues-Schumcher, Rolf Schumacher, Lothar Georg Viereck-Götte, Petra Lepetit
Turkish Journal of Earth Sciences
The 2.8 Ma İncesu ignimbrite is one of the most densely welded ignimbrites of the Cappadocian Volcanic Province. Estimates of areal extent and volume reveal at least 7,760 km^2 and 38 km^3 of erupted magma. The source area can be located beneath the northeastern flanks of the Erciyes Dağ-Koçdağ stratovolcano. Today, the ignimbrite typically forms relatively small plateaus or isolated remnants and caps on hill tops. Field characteristics of the deposit include a local dark-brown or black basal vitrophyre and horizontally zoned changes in colour which correspond to changes in modal composition. Upwardly increasing amounts of lithic fragments and pumice …
Field, Petrographic And Geochemical Characteristics Of The Hamit Alkaline Intrusion In The Central Anatolian Crystalline Complex, Turkey, Nurdane İlbeyli̇
Field, Petrographic And Geochemical Characteristics Of The Hamit Alkaline Intrusion In The Central Anatolian Crystalline Complex, Turkey, Nurdane İlbeyli̇
Turkish Journal of Earth Sciences
The Hamit pluton is one of the alkaline intrusions in the Central Anatolian Crystalline Complex (CACC). The pluton consists of nepheline syenite, pseudoleucite syenite, alkali-feldspar syenite and quartz syenite. The nepheline syenite and pseudoleucite syenite are cut by foid-bearing microsyenitic dykes, whereas the alkali-feldspar syenite and quartz syenite are cut by aplitic and silicic dykes. The predominantly peralkaline Hamit intrusive rocks possess field, petrographic and geochemical characteristics comparable to A-type granites. All intrusive rocks of this pluton show enrichment in LILE and LREE relative to HFSE. The Th/Yb versus Ta/Yb plot suggests that the intrusive rocks formed from an enriched …

Magma Interaction Recorded In Plagioclase Zoning In Granitoid Systems, Zigana Granitoid, Eastern Pontides, Turkey, Orhan Karsli, Faruk Aydin, M. Burhan Sadiklar
Turkish Journal of Earth Sciences
Plagioclase crystals characterized by compositional zoning are typical of the Zigana Granitoid (ZG), NE Turkey. The zoned crystals, which show textural equilibrium with the assemblage quartz + plagioclase + K-feldspar + hornblende + biotite + pyroxene + magnetite + ilmenite, exhibit oscillatory zoning. The zoned plagioclase crystals, ranging in size from 3 to 6 mm, are oval and larger than normal lath-shaped crystals. The zoned crystals are divided petrographically into two main types: (i) crystals zones only at their rims, with spongy cores; and (ii) completely zoned ones. Composition of the zoned crystals ranges from An_{23} (oligoclase) to An_{70} (labradorite). …
The Karakaya Complex: A Review Of Data And Concepts, Aral İ. Okay, M. Cemal Göncüoğlu
The Karakaya Complex: A Review Of Data And Concepts, Aral İ. Okay, M. Cemal Göncüoğlu
Turkish Journal of Earth Sciences
The Karakaya Complex in the Pontides consists of highly deformed and partly metamorphosed clastic and volcanic series of Permian and Triassic age. It is generally subdivided into two parts: The structurally lower part, called the Lower Karakaya Complex, consists of a mafic lava-mafic pyroclastite-shale-limestone succession metamorphosed in the greenschist and blueschist facies during the Late Palaeozoic or Triassic. The structurally upper part is made up of highly deformed Permian and Triassic clastic, volcaniclastic and volcanic rocks with exotic limestone blocks. There are currently two different models for the depositional setting and tectonic evolution of the Karakaya Complex. The rift model …

Significance Of The Volcanogenic Nilüfer Unit And Related Components Of The Triassic Karakaya Complex For Tethyan Subduction/Accretion Processes In Nw Turkey, Elizabeth A. Pickett, Alastair H. F. Robertson
Turkish Journal of Earth Sciences
The Tethyan Karakaya Complex extends east-west across northern Turkey from the Aegean coast to Iran (c. 1100 km), and is interpreted as a Mid-Late Triassic subduction/accretion complex. It comprises strongly deformed fragments of Triassic oceanic seamounts, mid-ocean ridge-type oceanic crust, trench-type sedimentary rocks (Ortaoba Unit) and Permian-Triassic continental fragments (Çal Unit). We focus on the Triassic Nilüfer Unit, which comprises altered basic volcanic and volcaniclastic rocks, volcanogenic sedimentary rocks, heterogeneous debris flow deposits, calciturbidites, siliceous pelagic sedimentary rocks and, in places, Triassic shallow-water limestones. The predominant lithologies are massive basalt and reworked basic pyroclastic deposits. Additional detrital lithologies include volcanogenic …

New Results On The Lithostratigraphy Of The Kazdağ Massif In Northwest Turkey, Mehmet Duru, Şükrü Pehli̇van, Yalçin Şentürk, Fatma Yavaş, Hüseyi̇n Kar
Turkish Journal of Earth Sciences
The high-grade metamorphic rocks of the Kazdağ mountain range, termed the Kazdağ Group, crop out as a tectonic window under the Karakaya Complex in northwestern Turkey. The Kazdağ Group forms a doubly plunging, NE-SW-trending anticliniorium. During our regional geological mapping of the Kazdağ Group, we have subdivided the metamorphic rocks into four formations. The lowermost unit is the Fındıklı formation, which comprises amphibole-gneiss, marble and minor amphibolite. It crops out mainly in the southern part of the Kazdağ Massif. The marble horizons within the Fındıklı formation have been named the Altınoluk and Babadağ marble members. The overlying unit, comprising metadunite …
Geology And Correlation Of The Ezine Zone: A Rhodope Fragment In Nw Turkey?, Laurent Beccaletto, Catherine Jenny
Geology And Correlation Of The Ezine Zone: A Rhodope Fragment In Nw Turkey?, Laurent Beccaletto, Catherine Jenny
Turkish Journal of Earth Sciences
In northwestern Turkey, the Denizgören ophiolite and its sedimentary substratum, the Ezine Group, are enigmatic geological objects whose evolution remains problematic. Based on long-term fieldwork, we here propose a solution for their genesis and correlation. The whole of the Ezine Group, more than three km thick, is characterised by the systematic occurrence of carbonate rocks in the greenschist facies. It has been subdivided into three conformable formations: the Geyikli Formation, with a slight terrigeneous detrital nature, (Middle)-Late Permian in age; the Karadağ Formation, with platform-type sedimentation with local detrital input, Late Permian (Djulfian) in age; the Çamköy Formation, with a …

Uppermost Triassic Limestone In The Karakaya Complex- Stratigraphic And Tectonic Significance, Aral İ. Okay, Demi̇r Altiner
Turkish Journal of Earth Sciences
Two important tectonostratigraphic units of the Karakaya Complex in northwest Turkey are: a lower metamorphic sequence of metabasite, phyllite and marble, called the Nilüfer Unit; and an upper clastic sequence with Permian and Carboniferous limestone olistoliths called the Hodul Unit. In northwestern Turkey, the Hodul Unit consists of arkosic sandstones, which pass upward into greywacke and siltstone with Permian and Carboniferous limestone blocks. A scarce macrofauna in the sandstones indicates a Norian age for the Hodul Unit. We report for the first time Norian-Rhaetian limestones, here named the Kaşal Limestone Member, from the Hodul Unit to the southwest of Balıkesir. …

Autochthonous Upper Permian (Midian) Carbonates In The Western Sakarya Composite Terrane, Geyve Area, Turkey: Preliminary Data, Necati̇ Turhan, Cengi̇z Okuyucu, M. Cemal Göncüoğlu
Turkish Journal of Earth Sciences
Permian limestones occur widely within the clastic units of the "Karakaya Complex" and are interpreted as allochthonous bodies or olistoliths. In the Kadirler area to the south of Geyve, however, Upper Permian (Midian) quartz sandstones and carbonates with a rich foraminifer fauna disconformably overlie a crystalline basement complex. This basement complex comprises metaclastic rocks, recrystallised limestones, metacherts, and metadiabases, and is intruded by granodiorites. The overlying basal conglomerates and quartzitic sandstones are dominated by pebbles from the basement complex and are followed upward by medium- to thick-bedded dolomites, dolomitic limestones and limestones. The foraminiferal assemblage with Neoschwagerina haydeni Dutkevitch and …

Upper Permian (Changxingian) Radiolarian Cherts Within The Clastic Successions Of The "Karakaya Complex" In Nw Anatolia, M. Cemal Göncüoğlu, Kiyoko Kuwahara, U. Kağan Teki̇n, Necati̇ Turhan
Turkish Journal of Earth Sciences
The arkosic sandstones with olistostromes within the "Karakaya Complex" in NW Anatolia to the south of Geyve include a thin layer of green chert with radiolaria. Based on the composition of Albaillellids, the radiolarian assemblage corresponds to the Neoalbaillella ornithoformis assemblage, and its age is assigned to the Changxingian (Late Permian). This is the first finding of synsedimentary radiolarian cherts within the Karakaya units and the indication of latest Permian rifting of the Karakaya basin within the Midian carbonate platform and its pre-Permian basement in the Sakarya Composite Terrane.

International Journal of Speleology
We observed cycles presented in a luminescent solar insolation proxy record from a speleothem from Jewel Cave, South Dakota, US. We found cycles of orbital precession with periods of 23 and 19 ka and of obliquity of 41 ka and many others from non-orbital origin in this sample. We determined the Solar origin of the cycles with durations of 11500, 4400, 3950, 2770, 2500, 2090, 1960, 1670, 1460, 1280, 1195, 1145, 1034, 935, 835, 750 and 610 years. It was done by their detection both in proxy records of speleothem luminescence, Δ14C and the intensity of the geomagnetic …

The Role Of The Environmental Archaeologist In The Study And Reconstruction Of Cave Palaeoclimate, Maria Gkioni
International Journal of Speleology
Man and environment are engaged in a continuous battle to impose themselves on one another. The results are found in environmental modifications or climatic oscillations and, as far as man is concerned, in the different character of cultural remains. Man responds to environmental changes by migrating or evolving technological innovations, both of which leave important remains that the archaeologist is called on to recognise and interpret during and after an excavation. They both also reflect the sociocultural responses to climatic stress. This paper refers to a specific case study, caves, which housed man and his activities from the very early …
