济南市长清区界首蛇纹岩矿地质特征及开发利用效益预测

Geological Characteristics and Utilization Benifits Predication of Serpentinite in Jieshou of Changqing District in Jinan City

摘要:

界首蛇纹岩矿为山东省较早开发的矿区，多用于提取钙镁磷肥，其地质条件较好，储量可观。区内矿脉断续出露长2400m，宽30~70m，延深100~200m，倾角60°~80°左右，矿体多出露地表，适于露天开采。1988年在蛇纹岩岩体中发现达到玉石标准的包裹体，并综合开发利用，矿山得以增产增值。目前属于村办开矿，开采不规范，导致乱采滥挖，至今矿山停采，并封矿。

Abstract:

Jieshou serpentine rock is an early developed mining area in Shandong province. It is used for the extraction of calcium magnesium phosphate. It has good geological conditions and large reserves. The length of mineral veins are 2400m and with the width of 30~70m. Its depth extension is 100~200m and the dip angle is about 60 °~80 °. Ore bodieds are majorly exposed on the surface which are suitable for open-pit mining. in 1988, inclusions which can reach the standard of jade are found in serpentine rock. Thus, serpentine rock is comprehensively explored and used. At present, the mines are majorly run by villages, and mining is not standardized. It has led to unchecked excavation, and mines have been closed.
