苏门答腊岛（印尼）成矿带的岩浆作用和源区及其对比
Magmatism and provenances of mineralization zones in Sumatra (Indonesia)and their comparisons to adjacent terrains
摘要
Abstract
This paper introduces the mineral distribution, igneous rock types and their geochemical characteris-tics within two mineralization zones (i.e. Cu-Au- and Sn-mineralization zones). Based on the litho-chemical data taken from our research project, the authors summary the geochemical characteristics of ore-bearing igneous par-ent rock and discuses the magmatic origin and source area in Cu-Au-mineralization zone. Meanwhile, a compari-son of rock types of magma and geochemistry-tectonic setting for Sn-mineralization zones in Sumatra Island to the adjacent Terrains is made here. The results of this study indicate that the ore-bearing parent rocks of Cu-Au mineralization zones in the West Sumatra Terrain are adakitic granitoids (SI-Type) were formed in the tectonic setting of volcano-arc in active continental margin(ACM)and the igneous matter came from partly melting of sub-ducted ocean-slab plus weakly melting-assimilation within mantle wedge(MASH),Whereas the ore-bearing ig-neous parent rock in tin mineralization zones within the‘tin island’of East Sumatra Terrain as well as“Sibumasu Terrain”are peraluminum granitoids(S-Type) belonging to tectonic setting of backed arc basin or rift within con-tinent after collision zone and were derived from the re-melting of crust and igneous fraction crystal. The geo-chemical data show that the East Sumatra Terrain and the West Sumatra Terrain may have the same deep igneous source area.关键词
