orebody

The orebody take the shape of prolate lenticle and appearing horizontal bedding.

区内有优质的硅藻土及硅藻粘土两矿。

The ore-bearing beds have a bimodal rock association and exhibit assembly characteristics of pyroclastic rock, orebody and exhalite.

含矿岩系为双峰岩组合，具有火山碎屑岩-矿体-喷气岩“三位一体”特徵。

The orebody is controlled by SN, NW faults and fissures, the ore deposit belongs to magmatic hydrothermalism-stratabound and compound magmatic hydrothermalism type one.

矿体受南北向、北西向断裂及裂隙构造控制,矿床成为岩浆热液—层控与岩浆热液复合型。

There is an obvious rock zonation from the middle to bothsides of the structural shatter zone, generally from marialite orebody through diopside-felsite,biotite-albitite to the host Proterozoic rocks.

构造破碎带的岩具有明显的对称分带性：破碎带的中心为钠柱矿体，向两侧依次为榍长英岩带、黑云母钠长岩带，并逐渐过渡为围岩。钠柱矿的成类型为沿构造破碎带产出的热液交代脉型。

Gold quartz vein is the major orebody which is controlled by E-W-extrusion fracture zone in the Damiaozi gold mineralized district.The granite-porphyry,spessartite and diabase are the major wallrock.

大庙子金矿化区内金矿体以英脉型为主,矿体的产出受东西向挤压破碎带控制,花岗斑岩和闪斜煌斑岩、绿岩是矿体的主要围岩。
