Hydrocarbon Potential Of The Kahramanmaraş And Elbi̇stan Areas, Yüksel Önem Jun 1991

Hydrocarbon Potential Of The Kahramanmaraş And Elbi̇stan Areas, Yüksel Önem

Bulletin of the Mineral Research and Exploration

The Taurus mountains, which developed in the conjoining zone of the Anatolian and Arabian Plates, underwent a disruption between Bolkar mountain and Engizek mountain. This can be explained by the fact that the area was traversed and transformed by two major strike-sup faults situated at Mersin-east Bolkar mountain-Kayseri in the west and Antakya (Hatay)-Elazığ-Bingöl in the east, In fact, the east-west oriented 200 km. wide area, covering the Gulf of İskenderun and the northern pan of Adana, was compressed and deflected as far as the north of Sarız and the Arabian Plate was dislocated prior to the faulting and moved …

Bulletin of the Mineral Research and Exploration

The presence of Nummulites ex gr. fabianii has been indicated in the Eocene sediments, and the stratigraphy of the region is briefly given. The rock units of Paleozoic, Mesozoic and Cenozoic ages crop out in the region. The Paleozoic sequence is composed of metamorphic rocks. This unit is tectonically underlain by the Mesozoic sequence formed of magmatic rocks. The Paleozoic and Mesozoic rocks arc unconformably overlain by the sandstone and algal limestones of the Upper Lutetian age. Algal limestone contains genera of the Foraminifcra such as Nummulites perforatus (Montfort). Assilina spira (de Roissy), Alveolina fusiformis Sowerby, Alveolina elongata d'Orbigny, Fabiania …

Elemental Relationships In Rock Varnish As Seen With Scanning Electron Microscopy And Energy Dispersive X-Ray Elemental Line Profiling, Robert Raymond Jr., Steven L. Reneau, Charles D. Harrington Jan 1991

Elemental Relationships In Rock Varnish As Seen With Scanning Electron Microscopy And Energy Dispersive X-Ray Elemental Line Profiling, Robert Raymond Jr., Steven L. Reneau, Charles D. Harrington

Scanning Microscopy

The heterogeneous nature of rock varnish requires a thorough understanding of elemental and mineralogic compositions before chemical variability of rock varnish may be confidently related to varnish age or to past geochemical environments. Elemental relationships in rock varnish were examined using scanning electron microscopy in conjunction with an elemental line profiling routine using semi-quantitative, energy-dispersive x-ray analysis. Results of our analyses suggest: 1) variations in cation concentrations used in varnish cation-ratio dating relate more specifically to variations in detritus concentration within the varnish than to element mobility as defined by weathering indices; 2) Mn:Fe ratios may be a poor indicator …


Scanning Electron Microscopic Analysis Of Rock Varnish Chemistry For Cation-Ratio Dating: An Examination Of Electron Beam Penetration Depths, Steven L. Reneau, Roland C. Hagan, Charles D. Harrington, Robert Raymond Jr. Jan 1991

Scanning Electron Microscopic Analysis Of Rock Varnish Chemistry For Cation-Ratio Dating: An Examination Of Electron Beam Penetration Depths, Steven L. Reneau, Roland C. Hagan, Charles D. Harrington, Robert Raymond Jr.

Scanning Microscopy

Rock varnish is a microns-thick manganese- and iron-rich coating that forms on exposed rock surfaces in arid and semi-arid environments, and empirical correlations of the varnish cation ratio (K+Ca):Ti with age have been used to estimate ages of geomorphic surfaces. One method of obtaining varnish chemistry for cation-ratio dating involves scanning electron microscope (SEM) energy dispersive x-ray (EDX) analysis of natural varnish surfaces. The chemical analyses of rock varnish with SEM/EDX utilize a sequence of accelerating voltages to vary penetration depths into the sample. Using elemental x-ray maps of natural varnish surfaces obtained by SEM/EDX analysis, penetration into the substrate …


Barium Concentration In Rock Varnish: Implications For Calibrated Rock Varnish Dating Curves, C. D. Harrington, D. J. Krier, R. Raymond Jr., S. L. Reneau Jan 1991

Barium Concentration In Rock Varnish: Implications For Calibrated Rock Varnish Dating Curves, C. D. Harrington, D. J. Krier, R. Raymond Jr., S. L. Reneau

Scanning Microscopy

Cation-ratio dating of rock varnish is a recently developed technique for obtaining surface exposure ages of a wide variety of geomorphic surfaces. As originally proposed, the technique utilizes a ratio among minor cations [(K+Ca)/Ti] in rock varnish. Although this varnish cation ratio is related to the Ti concentration, it can also be affected by the presence of Ba that may be partially included in the analyzed concentration of Ti. Barium is a minor constituent found in virtually all rock varnishes sampled from the Lake Mead area, Las Vegas Valley, and the Crater Flat region of southern Nevada. Barium is heterogeneously …


Trees And Livestock : A Productive Co-Existence, Richard Moore Jan 1991

Trees And Livestock : A Productive Co-Existence, Richard Moore

Journal of the Department of Agriculture, Western Australia, Series 4

Trees, as part of farming can help to combat land degradation problems and produce a good economic return from timber at the same time. For example, there is now clear evidence that planting trees can help combat salinity by lowering water-table levels. Trees can also substantially improve overall farm productivity by providing shelter for pastures and livestock. The challenge is to find practical and economical methods of integrating trees and farming. A combination of widely-spaced trees and livestock is one promising method. This article describes the benefits of this type of agroforestry to farmers, suitable locations and how to practice …


Unique Co-Operative Landcare Venture In The Avon Catchment, Darrel Brewin, John Collett Jan 1991

Unique Co-Operative Landcare Venture In The Avon Catchment, Darrel Brewin, John Collett

Journal of the Department of Agriculture, Western Australia, Series 4

The Avon catchment is bustling with landcare activity generated by a unique co-operative venture between farmers, the Department of Agriculture, the National Soil Conservation Program and Alcoa of Australia Ltd. The Avon Catchment Landcare Program was initiated by the Department of Agriculture and Alcoa, in support of the national Decade ofLandcare. The program provides financial, human and technical resources to undertake catchment and farm planning and demonstrations of rehabilitation techniques that tackle soil and water degradation problems. We know that without specially planned landcare programs and substantial changes in land management, land degradation will continue and further losses of agricultural …

Pleistocene Mammals From The South Sulphur River, Hunt County, Texas, Leo Carson Davis, Kenneth M. Ball Jan 1991

Pleistocene Mammals From The South Sulphur River, Hunt County, Texas, Leo Carson Davis, Kenneth M. Ball

Journal of the Arkansas Academy of Science

Preliminary collecting and excavating along the South Sulphur River has produced a diverse list of fossil mammals. The pampathere, Holmesina septentrionalis, and the large armadillo, Dasypus bellus, with their southern affinities from the extinct megafauna, were found in association with Microtus pennsylvanicus, which has a northern distribution at present. This combination of species argues for climatic conditions and biotic communities during the Pleistocene that have no modern counterparts.
