东秦岭大别山段斑岩型钼(钨、铜)矿床地质特征 总被引：4，自引：1，他引：3
东秦岭大别山段矿化中酸性小岩体集中分布在东秦岭钼(钨、铜)矿带东段,呈带状沿深大断裂两侧分布,受构造控制明显.已发现主要钼矿床属斑岩型,成因多与中生代中酸性花岗质斑岩有关.根据斑岩型钼(钨、铜)矿床地质特征,通过控岩控矿构造、围岩蚀变、矿体特征、矿石物质组份及其成矿机制等方面的研究,把东秦岭大别山段斑岩钼(鸽、铜)矿划分为浅成-超浅成斑岩钼(铜)矿床,中-深成斑岩-夕卡岩钼(钨、铜)矿床两种类型. 相似文献

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ1 roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
