A Standard Biostratigraphic Sequence for the Devonian of Western North America

美国西部泥盆纪的拟议研究涉及五个领域的努力。1. 腕足动物系统学：将描述和说明一个新的腕足动物属。此外，志留纪和泥盆纪的灵虫部分将为修订后的腕足类论著作准备。将整理泥盆纪腕足类一般动物的精确范围数据。2. 通过对5个实测剖面和229个化石样品的综合分析，对中、上泥盆统动物层序进行了研究和细化。预计在中泥盆统顶部附近将发生带状细化。将在内华达州中部研究横跨弗拉斯纪-法门纪边界的晚泥盆世的沉积史。当时外陆架盆地因台地出露而沉积了石英砂。4. 它的目的是根据过去14年收集的数据，分析罗伯茨山脉前缘边缘两个关键地区的地质情况。5. 准备一篇关于美国西部古生代的综述论文

Proposed research in the Devonian of the western U.S. involves five areas of endeavor. 1. Brachiopod systematics: one new brachiopod genus will be described and illustrated. In addition, the section on Silurian and Devonian spirifers will be prepared for the revised Brachiopod Treatise. Precise range data will be collated for Devonian brachiopod general. 2. The Middle and Upper Devonian faunal sequence will be studied and refined by synthesis of five measured sections and 229 fossil samples. Zonal refinement is anticipated near the top of the Middle Devonian. 3. The depositional history of an interval of the Late Devonian spanning the Frasnian-Famennian boundary will be studied in central Nevada. Quartz sands were deposited in the outer shelf basin at that time as a result of platform emergence. 4. It is intended to analyze geology in two critical areas along the frontal margin of the Roberts Mountains thrust from data gathered during the last 14 years. 5. A review paper is planned for preparation on the Paleozoic of the western U.S.
