| 中文摘要: |
| 本文应用有限单元法,动态地模拟了安基山铜矿区花岗闪长斑岩岩浆侵入期和岩浆期后热液阶段的构造应力场,由此探讨矿区构造产生的力学机制、构造应力场与地球化学场之间的关系以及成矿溶液运移的趋势。从构造动力角度解释了该矿区中的矽卡岩型和脉型矿体主要产在东接触带,而斑岩型矿化主要赋存于岩体西侧浅部的原因。 |
| 英文摘要: |
| This paper models dynamically the stress fields at the magmatic intrusive period and the postmagmatic hydrothermal stage of the granodiorite porphyry using the finite element method,and discusses the dynamic mechanism of structural forming,the relationship between stress field and geochemical field and the regularity of ore-bearing fluid flow tendency at the Anjishan mining area,Jiansu province.The structural dynamics,can interpret why ore-bodies of skarn and vein types are mainly in the east of contact zone of the body of granodiorite porphyry and the ore-bodies of the porphyry type in the western upper body of porphyry. |
