查询词典 silication

Field obserbation and laboratory study indicate the main type of rock alterationwere K-feldsparization, biotitization, sericitization, silication, epidotization,chloritization and carbonatization. From early to late, these alteration could dividedinto three epochs: early-stage was K-feldsparization-biotitization, middle-stage wasquartzification -sericitization, late-stage was silication, carbonatization, epidotizationand chloritization.

In ore body, K-feldsparization is widely distributed, silication ispockety, the other alterations have obvious vertical zoning, from upper to lower is:biotite zone→sericite zone→propylitic zone (epidote-chlorite-calcitization zone).

在空间上，钾长石化分布较广，硅化分布不均，其它蚀变垂直分带现象比较明显，由下至上是：黑云母化带→绢云母化带→青盘岩化(绿泥石-绿帘石-方解石化)带。

Metallization occurred in rock alteration, the alteration types are silication, seritization, pyritization and carbonation etc. Rock alteration is a good criteria for ore prospecting.

Silicons are the most in the earth's crust, silicon oxidize the silicon form and exist by two more, is rich in two high-temperature karst which oxidize the silicon, under the function of the pressure, and soak trunks outside gradually inside, there is a crystallization course, it is the silication course.

地壳中硅是最多的，硅多以二氧化硅形式存在，富含二氧化硅的高温岩溶，在压力的作用下，从外及内逐渐浸润树干，并有个结晶过程，便是硅化过程。

Summarize the condition that the silicified wood forms, must possess: The volcano breaks out or other reasons make the stratum subside, the trees are buried deeply, the environment close, bear the high pressure, stand the infiltration of the high-temperature karst taking oxidizing silicons two times as principal ingredients, go through it with the endless long river that must be written every year, just reach the silication right fruit after all.

概括硅化木形成的条件，必须具备：火山暴发或其他原因使地层陷落、树木深埋、环境封闭、承受高压，并经受以二氧化硅为主要成分的高温岩溶的浸润，历经以千万年记的漫漫长河，才终达硅化正果。

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.
