本文所描述的床板珊瑚和日射珊瑚化石是笔者1974年随中国地质科学院地矿所和新疆地质局区域地质调查大队组成的地层分队(以下简称地层队)共同采集的。这些化石分布在精河县基夫克河上游,尼勒克县尼勒克河上游及霍城县果子沟地区。地理座标为北纬44度—44度30分,东经81度—83度。1953年苏联地质保矿部第十三航测大队曾在区内做过1:20万区域地质测量,其成果收集在“伊犁专报”中。他们将该区“志留系”划分为六个岩组。1974年地层队对该区早古生代地层进行了详细调查,采集了大量古生物化石,根据古生物特征和岩相变化规律,对志留系进行了重新划分。
The coral and sun-coral fossils described in this article were collected jointly by the author and the stratigraphic unit (hereinafter referred to as stratigraphic team) formed by the Institute of Geology and Mineral Resources of Chinese Academy of Geological Sciences and the Xinjiang Regional Geological Survey Brigade in 1974. These fossils are distributed in the upstream of the Kefuk River in Jinghe County, in the upper reaches of the Nilek River in Nilek County and in the Fruit Valley area of Huocheng County. The geographical coordinates of 44 degrees north latitude -44 degrees 30 minutes east longitude of 81 degrees -83 degrees. In 1953, the thirteenth navigational brigade of the Department of Geology and Mineral Resources of the Soviet Union had conducted 1: 200,000 regional geological surveys in the area, and the results were collected in Ili Special Report. They divided the Silurian in the area into six rock groups. In 1974, the stratigraphic team conducted a detailed investigation of the Paleozoic strata in the area, collected a large number of paleontological fossils, and re-divided the Silurian according to paleontological features and lithofacies changes.
