长石

Some other older zircons with 206Pb/238U ages of 932 to 2443Ma 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。

Hydrothermal sedimentary albitite in the Upper Paleozoic in the South Qinling is closely related to many large-superlarge lead-zinc deposits in the south Qinling orogenic belt.

The Dagougu gold-bearing albitite, which is characterized by bedding and massive struc-ture, is mainly stratiform and 1enticular in shape, and also occurs as veins in the Late Proterozoicschist.

粤西大沟谷一带钢长石岩主要以层状、透镜状及脉状产于震旦系乐昌峡群变质片岩中，具块状及条带状构造，是大沟谷金矿的主要赋矿岩石。

This paper reports the results of highly precise zircon SHRIMP U-Pb dating of quartz albitite in the volcanic-sedimentary series of the Tuolugou cobalt deposit, Golmud, Qinghai. Analyses of eight spots presented 206Pb/238U ages of 455 to 483Ma with a weighted mean age of 468±9Ma, which represents the timing of submarine volcanic exhalation in this area. Therefore, the age of the host rocks of the Tuolugou ore district is redefined as Ordovician, which implies that regionally the main part of the Naij Tal Group should be Early Paleozoic in age.

青海格尔木驼路沟矿区赋矿火山－沉积岩系中的石英钠长石岩样品锆石SHRIMP U-Pb精细测年结果表明，该岩石具有一组8个测点构成的455~483Ma的206Pb/238U年龄数据，加权平均年龄为468Ma±9Ma，应代表本区海底火山喷流作用的时间，因此重新厘定了矿区内含矿岩系的时代为奥陶纪，同时，这一年龄指示区域上纳赤台群主体的时代应为早古生代。

Na-rich rocks include albitite ,arfvedsonite-bearing albitite dyke,arfvedsonite dyke,and arfvedsonite-bearing .

The albitite is characterized by enrichment of Na2O and SiO2 as well as trace elements suchas Au, As Sb,B and depletion of MgO, MnO,K,O and trace elements which include Cu, Ni,Co,Pband Zn.

钠长石岩富Na、St、Al、Mg、Mn、K，在微量元素方面富An、As、Sn、B、Cu、Ni、Co、Ph、Zn，稀土元素的含量较低，配分模式为平缓右倾曲线。

This study takes the reservoir of the Kela 2 gas field of the Tariam basin, the western China, as an example for understanding the relationship between the porosity and permeability and autogenetic minerals and textures of the clastic rocks on the vertical depth scale. The secondary pores are essential reservoir space in this gas field, moreover, their origin is closely related to dissolution of the frame grain of plagioclase and the cements of calcite.
