Basic characteristics and genesis of Stratiform albitite 层状钠长石岩的基本特征及成因分析
Some other older zircons with 206Pb/ 238U ages of 932 to 2443 Ma were brought from Precambrian basement rocks at depth by strong submarine volcanic eruption and then deposited in quartz albitite together with hydrothermal fluids. 其他较老年龄锆石是由强烈的海底火山喷发作用从深部基底物质中带出的,并与热水流体一起沉积下来,赋存在石英钠长石岩中。
A kind of jasperoid-like striped albitite is discovered recently in a Devonian metallogenic basin in the eastern Qinling. 在秦岭东段泥盆系中新发现一种似碧玉层纹钠长石岩,发育有与中泥盆统同样良好的韵律层。
The extrusive rock unit includes basalt, andesite, boninite and albitite as well as breccia and tuff. 喷出岩单元不仅仅由玄武岩组成,还包括安山岩、玻安岩、钠长岩以及角砾岩、凝灰岩等。

The formation of secondary quartz, albitite, calcite and laumontite affected the storage physical properties of sandstone in different degrees. 次生石英、钠长石、方解石和浊沸石等的形成不同程度地影响了砂岩的储集物性。

Discovery and its significance of jasperoid-like striped albitite in the Devonian System of the Qinling Mountains 秦岭东段泥盆系中似碧玉层纹钠长石岩的发现及其意义
In addition, the stockwork pipe ( quartz-albitite) can be used as a mark of prospecting lead-zinc deposits in the northern margin of Qaidam Basin. 由于网脉状蚀变岩(石英钠长岩)与成矿系统的密切关系,它可作为柴达木盆地北缘滩涧山群中寻找铅锌矿的重要找矿标志。
There is a close relationship between formation of deposit and hot water sedimentary rocks, which mainly consist of albitite and cherts oriented. 矿床的形成与热水沉积岩关系密切,热水沉积岩以钠长石岩和硅质岩为主。
