为了研究昆明盆地的形成、演化及第四纪有关矿产与环境地质,一九八二年云南省地质矿产局在滇池海埂施工了科研钻孔,编号为滇池科研1号井(简称科1井)。本文就该孔岩心的沉积物的结构构造、生物、沉积序列变化和物探测井资料的研究,对其中厚达490米的第四纪地层的沉积相、沉积环境及其演变趋势进行分析讨论。
In order to study the formation and evolution of the Kunming Basin and related Quaternary minerals and environmental geology, in 1982, the Bureau of Geology and Mineral Resources of Yunnan Province conducted a scientific drilling in Dianchi Lake. The No. 1 Dianchi Scientific Research Well ). In this paper, the sedimentary facies, sedimentary environment and evolution trend of Quaternary strata, which are up to 490 meters in thickness, are analyzed and discussed based on the study of structural structure, biological and sedimentary sequence changes and geophysical logging data of the sediments in this hole.
