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方面的努力。1.腕足类系统学：描述和图解腕足类一新属。此外，关于志留纪和泥盆纪尖吻类的部分将在修订的腕足类论文中编写。泥盆纪腕足类将军的精确测距数据将被整理出来。2.综合5个测量剖面和229个化石标本，对中、上泥盆统动物群序列进行研究和提炼。预计在中泥盆世顶部附近将进行带状精炼。3.将在内华达州中部研究跨越弗拉斯-法门期界线的晚泥盆世一段的沉积史。由于台地的涌出，当时的外陆架盆地沉积了石英砂。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逆冲的两个关键地区的地质情况。5.计划编写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.
