Analysis And Interpretation Of The 5,000 Ft (1,538 M) Red-Bed Sequence Encountered In The Sparks Et Al. #1-8 (Michigan Basin Deep Borehole), John H. Fowler Dec 1979

Analysis And Interpretation Of The 5,000 Ft (1,538 M) Red-Bed Sequence Encountered In The Sparks Et Al. #1-8 (Michigan Basin Deep Borehole), John H. Fowler

Masters Theses

A 5,000 ft (1,538 m) pre-Mt. Simon (Upper Cambrian) red-bed sequence, encountered in the Gratiot County deep borehole (Sparks et al. #1-8) and herein named the North Star Formation, consists of undeformed recurring beds of immature arkosic sandstone 2 to 34 in (5 to 85 cm) thick. These beds grade upward from erosional basal contacts into mudstone units 1 in to 12 ft (3 cm to 3.8 m) thick. Within the sandstones, grading, horizontal lamination, and crossstratification define Bouma intervals "a", "b", and "c", which combine to form incomplete Bouma sequences. Mudstones exhibit abundant horizontal laminations. Secondary sedimentary structures (load …

Postglacial Environmental History Of A Marl Lake Site In Kalamazoo County, Southwestern Michigan, Valerie A. Naeve Apr 1979

Postglacial Environmental History Of A Marl Lake Site In Kalamazoo County, Southwestern Michigan, Valerie A. Naeve

Masters Theses

The depositional and ecological history of Oakland Bog, a relic Wisconsinan (16,500+300 years B.P.) lake site is interpreted from pollen stratigraphy, molluscan faunal assemblages and sediment facies. The lake basin, which probably formed after the melting of a late Wisconsinan buried ice block in the Kalamazoo Moraine Complex, is irregular, steep-sided and floored by glacial till. The till is overlain by as much as 7.6 meters of lacustrine marls which extend over an area of nearly 0.5 km2. Basal marls are characteristically medium gray, clayey, and contain abundant calcified stem fragments of charophytes; however, the overlying marls display …
