| 摘 要： | 大青山地区碎屑岩型金矿控矿系统表现为:古元古代大陆裂陷槽构造环境为金矿成矿提供背景条件(物质场、能量场、空间场),该环境下沉积的二道凹群中部的红山沟组下部复理石建造为金矿成矿提供物质条件,该建造在造山早期由拉伸机制形成的顺层滑脱剪切带控制成矿带,剪切带内的同期次级褶皱构造(尤其是向斜、向形构造)为金矿成矿提供容矿空间;提出了层位(复理石建造)、顺层滑脱剪切带及相关次级褶皱构造三者叠加控矿的金矿控矿型式。 |

| Abstract: | The clastic carbonate rock-type gold deposit -control system in Daqingshan area is characterized by continental aulacogen tectonic background, the flysch formation at the Lower Hongshangou Formation of Middle Erdaowa group and the bedding detachment shear zone. The aulacogen provided the metallogenic background condition （i. e. Erdaowa group was deposited under the background） including the ore-forming materials, energy and space. The flysch formation provided the ore-forming materials and the ore-forming space, the bedding detachment shear zone and the sub-scale folds, especially for the syncline and synform structure in the shear zone which was formed by extension mechanism during the early aulacogen close- orogeny period. Then is put forward three-factor-ore-control model of the flysch formation and the overprinted bedding detachment shear zone and the sub-scale folds. |
