四川攀西地区几个小型镁铁-超镁铁岩体含矿性的铂族元素示踪
|
摘要
峨眉山大火成岩省内带,四川攀西地区的杨合伍、黄草坪和清水河等镁铁-超镁铁岩体分布在南北向的安宁河断裂和磨盘山-元谋断裂之间。分析表明,这些岩体无矿岩石与金宝山、杨柳坪、力马河等含矿岩体无矿岩石具有相似的铂族元素组成,普遍较高的Cu/Pd比值暗示这些岩体的母岩浆在侵入到目前层位前经历过硫化物熔离作用。定量模拟计算表明,原始岩浆经过大约0.01%的硫化物熔离作用形成了杨合伍岩体母岩浆,经过0.035%硫化物熔离形成了黄草坪和清水河岩体的母岩浆。根据硫化物熔离情况,认为杨合伍等岩体底部可能形成Ni-Cu-(PGE)硫化物矿床,而黄草坪和清水河岩体之下及附近可能存在Ni-Cu硫化物矿化的岩体。
Sulfides-bearing mafic-ultramafic intrusions in the central zone of the Emei Shan large igneous province within Panxi area, such as Yanghewu, Huangcaoping and Qingshuihe, are distributed between the NS-striking Anninghe fault and Mopanshan-Yuanmou fault. The barren rocks in these intrusions are similar to barren rocks in such ore-bearing intrusions as Jinbcaoshan, Yangliuping and Limahe in platinum-group element composition. High Cu/Pd values of the rocks of the intrusions indicate that the parental magmas had undergone sulfide segregation before their intrusion into the present horizon. Model calculations show that the magma underwent about 0.01% sulfide segregation before the formation of the Yanghewu intrusion, and the magmas experienced 0.035% sulfide separation before the formation of the Huangcaoping and Qingshuihe intrusions. There probably exist Ni-Cu-(PGE) sulfides at the bottom of the Yanghewu intrusion and Ni-Cu sulfide mineralizations in hidden intrusions beneath the Huangcaoping and Qingshuihe intrusions or other neighboring intrusions.
