摘要
燕山早期中-酸性岩浆岩侵入于蓟县系铁岭组、青白口系下马岭组地层中.辉钼矿化分布于岩体内部及其围岩中.本文讨论了花岗斑岩和闪长岩体的地质特征、成岩期次、岩石学、岩石化学特征及其含矿性;论述了矽卡岩一斑岩型钼矿床的成矿地质条件、围岩蚀变、矿床特征和矿床成因.
In the early stage of Yanshan Movement medium-acidic magmatic rock intruded in Tiering Formation of The Jixian System and The Xiamaling Formation of Qing baikou System. Molybdenum mineralization occur inside and outside the rock mass. This paper presents the features of the intrussives (granitic porphyry and diorite), their formation stages and the probability of Mo - metallogeny. Furtherly are discussed geological condition under which skarn - porphyritic molybdenum ore deposit are formed, alterations in wall rocks and the genesis of the Mo-deposit.
