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.

通過野外觀察及室內(nèi)研究表明国产欧美日韩另类VA在线，圍巖蝕變類型主要有鉀長石化、黑云母化欧美一级婬片人妻欧美电影、絹云母化久久深夜福利亚洲网站、硅化、綠簾石化无码aaa、綠泥石化和碳酸鹽化伊人免费视频，從早至晚可分為三期：早期為鉀長石-黑云母化；中期為石英-絹云母化涩多多在线观看；晚期為硅化操逼北京老妇、碳酸鹽化和綠泥石、綠簾石化sejjzzcom。

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).

在空間上欧美爆乳激情A片，鉀長石化分布較廣，硅化分布不均一级群交视频，其它蝕變垂直分帶現(xiàn)象比較明顯午夜电影网址，由下至上是：黑云母化帶→絹云母化帶→青盤巖化(綠泥石-綠簾石-方解石化)帶国产高清黄色。

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

礦化垂直分帶還表現(xiàn)在礦物組合、礦石結(jié)構(gòu)構(gòu)造黄色日逼、圍巖蝕變4455vw永久亚洲、成礦溫度、鹽度xxxx5566、氣液比下载日韩精品视频网站大全免费观看、鉛同位素比值等方面。

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.

地殼中硅是最多的国产一级视频精品，硅多以二氧化硅形式存在亚洲国产偷窥，富含二氧化硅的高溫巖溶，在壓力的作用下国产抇久久一精品A片，從外及內(nèi)逐漸浸潤樹干清纯唯美第一页，并有個結(jié)晶過程，便是硅化過程在线观看国产黄色视频高清。

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.

概括硅化木形成的條件欧美人交视频在线观看，必須具備：火山暴發(fā)或其他原因使地層陷落、樹木深埋www.久久艹、環(huán)境封閉国产欧美综合在线一区二区91、承受高壓，并經(jīng)受以二氧化硅為主要成分的高溫巖溶的浸潤www.193yw.com，歷經(jīng)以千萬年記的漫漫長河爱操在线视频精品，才終達硅化正果。
