Illite is a layered clay mineral similar to mica, also known as hydromuscovite. The flaky or strip-like crystals of illite are very small, and they generally appear to us as earthy. Because of impurities, illite is generally yellow, brown, green and other colors, but if the purity is high, it should be white. Much illite is formed by weathering of muscovite or potassium feldspar, and illite can be transformed into other clay minerals. The crystals are mainly monoclinic hydrous layered silicate minerals. In the formula, R2+ represents divalent metal cations, mainly Mg2+﹑Fe2+ and so on. The crystal structure is basically the same as that of muscovite, and it also belongs to the 2-octahedral type of the 2:1 structural unit layer. Crystals have polymorphic variants such as 1M, 2M, 1Md and 3T. Unlike muscovite, the amount of K+ in the interlayer is less than that of muscovite, and there are water molecules. Therefore illite is also called water muscovite. Others use…

On September 15, 2021, our department accepted the application for sea use of the Zheneng Zhoushan Liuheng LNG Terminal Project. According to the relevant requirements of the “Notice of the Ministry of Natural Resources on Regulating the Compilation of Demonstration Materials for the Use of Sea Areas” (Zhi Zi Gui [2021] No. 1), the sea area use demonstration report of this project is now publicized, and the publicity period is September 23, 2021 – October 11 (10 working days). If you have any comments, please send feedback to hyhds_public@mail.mnr.gov.cn. The project announcement information is as follows: 1. Applicant for sea area use: Zhejiang Zheneng Liuheng LNG Co., Ltd. 2. Compilation unit of the sea area use demonstration report: Zhejiang Water Conservancy and Estuary Research Institute. 3.

On the morning of September 7, Zhong Ziran, a member of the Party Leadership Group of the Ministry of Natural Resources and Director of the China Geological Survey, visited Wang Qingxian, Deputy Secretary of the Anhui Provincial Party Committee and Governor of Anhui Province, in Hefei, Anhui Province, to support and serve the high-quality economic and social development of Anhui Province and the construction of ecological civilization. In-depth discussion, and jointly witness the signing of the strategic cooperation agreement between the two parties. The two sides believe that the signing of the strategic cooperation agreement is an important measure to implement the spirit of General Secretary Xi Jinping’s important speech when he visited Anhui Province, strengthen the “two persistences” and realize the “two greater”. According to the agreement, the two parties will conduct comprehensive survey, evaluation and monitoring of natural resources, ecological geological survey of important ecological function areas, survey of clean energy and strategic mineral resources in important metallogenic…
