orebody

1.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个品级。

2.The orebodies occur within or near the exocontact of intrusive rocks and above the hidden igneous rocks.

产于岩体外接触带及其附近和隐伏岩体上方。

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

含岩系为双峰岩组合，具有火山碎屑岩-体-喷气岩“三位一体”特徵。

4.Orebodies in sedirmentary rock hosted Au deposits are discrete hypogene and epigenetic masses usually hosted in a fault zone, breccia mass, or lithologic bed or unit.

沉积岩床的体是一些不连续的内或后地质体,通常赋存于断裂带、角砾岩体或岩层(岩性单位)中。

5.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：破碎带的中心为柱体，向两侧依次为榍透辉长英岩带、黑长岩带，并逐渐过渡为围岩。柱的成因类型为沿构造破碎带产出的热液交代脉型。

6.The study shows that the gold quartz vein is the largest orebody which was controlled by E-W extrusion fracture zone.The kaligranite and spessartite are the largest wallrocks.

研究表明大庙子—板庙子化区内体以英脉型为主,体的产出受东西向挤压破碎带控制,钾质花岗岩和闪斜煌斑岩是体的主要围岩;

7.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.

大庙子化区内体以英脉型为主,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、辉绿岩是体的主要围岩。

8.Copper mineral belts can be easily seen in orebody.There has clear border between footwall and base of orebody, but it changes gradually from ore to its hangingwall.

铜化具有明显的分带特征,体底板与围岩之间界限清楚,顶板与围岩之间呈渐变过渡;

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

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