滇池湖盆位于云南省中部,是该省内较大型的山间盆地之一。盆地中沉积了较厚的新生代地层,并有多层褐煤和油气显示。 为解决昆明地区的能源和用水问题,建国以后有许多地质单位和研究者在本区作过大量的地质勘探和研究工作,为进一步研究该盆地提供了丰富的资料。一九七九年以来,笔者在野外工作的基础上,对滇池东北侧施工的Tk-9和Tk-15孔的岩心进行了较系统的沉积相、古地磁和孢粉等工作。本文就已获得的部分资料,提出一些看法。
Dianchi Lake Basin is located in the central part of Yunnan Province and is one of the larger mountain basins in the province. In the basin, thicker Cenozoic strata were deposited and multi-layer lignite and oil and gas were revealed. In order to solve the problem of energy and water consumption in Kunming, many geological units and researchers made a lot of geological exploration and research work in this area after the founding of the People’s Republic of China, which provided abundant information for further study of the basin. Since 1979, based on field work, the author has carried out relatively systematic sedimentary facies, palaeomagnetic and sporopollen on the cores of wells Tk-9 and Tk-15 constructed on the northeast side of Dianchi Lake. This article has obtained some of the information, put forward some views.
