侏罗纪晚期,砂岩物源来自于稳定的被动大陆边缘,早白垩世Barremian期砂岩物源来自于被动大陆边缘和火山弧的双重供应,随地层变新火山物质的输入逐渐增加,至Albian早期达到顶峰。

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。

A complex suite of intermediate-basic to intermediate-acid and relatively alkaline volcano-intrusive rocks of dominant andesitic composition and a group of iron ore deposits of somewhat different genetic types associated with them, including late magmatic, pegmatitic, pneumato-hypothermal, pyrometasomatic, meso- to epithermal deposit and the possible ore-magmatic and volcanic-sedimentary deposits, which are the successive products of the magmatic evolution, widely distributed in the faulted basins in the mi...

在长江中下游的若干断陷盆地中,发育着一套中、基性到中、酸性而含碱较高的、并以安山质为主的火山-侵人杂岩,与这一套有关的岩浆的演化过程相联系,形成一组从岩浆晚期到伟晶、高温气液、高温接触交代、中、低温热液及可能的矿浆充填、火山喷发沉积成因的铁矿床。

This paper employs clay stone analysis to Permian-Triassic boundary strata from three deep water sections, Duanshan, Nashui and Liuqiao, located in Guangxi and Guizhou region, southwestern China. The result shows that clay stones from the three localities are composed of illite-montmorillonite mixed layer, montmorillonite and kaolinglite. There are rock fragments such as bipyramid quartz and zircon which are related to volcanic process found in all the sections except in Nashui section.
