摘要燕山期火山次火山浅成斑岩金矿成矿系列构成了赣北地区一个重要的金矿成矿系列。 |
| 4. | Cihai iron ore deposit is a subvolcanic - ore pulp intrusive - hydrothermal scouring replacement deposit , which is occurred in the rift of the southern margin of the eastern tianshan mountains in the lower permian epoch
摘要磁海铁矿床产于早二叠世东天山南缘裂陷槽大地构造环境中，为次火山矿浆侵入热液充填交代矿床。 |
| 5. | Based on the derivation of metallogenic matters , mineralization and wallrock conditions , the gold deposits are subdivided into three main types : volcanic thermal type , subvolcanic rock - shallow to ultra - shallow porphyry thermal type , and concealed explosive breccia type of gold deposits
根据其金矿成矿物质来源、成矿作用及产出的围岩条件可划分为火山热液型、次火山浅成斑岩热液型和隐爆角砾岩型金矿床。 |
| 6. | The subvolcanic hydrothermal processes show a series responses of alteration rocks with some regularity of space and time evolutions , the main metallogensis was between the silicate alterations ( high - middle temperature and prssure ) and sulfide alterations ( low temperature and pressure )
次火山水热活动有一系列不同类型，并具一定空间分布和时间演化规律的蚀变岩响应，主期成矿作用发生在中高温压硅酸盐蚀变与中低温压硫化物蚀变之过渡阶段。 |
| 7. | Permian series distributed widely in the baisin . lower permian series was composed of acid , neutral , and basic volcanics , subvolcanic rocks , volcanoclastic rocks and few normal sedimentary rocks . from western to eastern , the volcanics transited from acid volcanics to neutral and basic volcanics
二叠系在盆地内部分布广泛，下二叠统卡拉岗组主要发育酸、中、基性火山岩、次火山岩、火山碎屑岩及少量正常碎屑岩，由西向东火山岩由中、酸性向中、基性过渡。 |
| 8. | Primarily summerization on geological characteristics and new progress in scientific research of these deposits are given in this paper , the author proposes that mineralogenesis of mpcd type gold deposit is closely related to meso - neozoic volcanic - subvolcanic action ( cryptoexplosive breccia ) , tectonic movement and maturation of organic material
