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。

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.
