The petrological study and studies in element and isotopic geochemistry indicate that the pluton belongs to high-potassium calc-alkaline I-type granite, whose magma came from basic basalt in the thicken crust bottom by partial melting, and are of syn-collisional features. The pluton provides a direct petrological evidence of the plate collision and amalgalation.

The change of REE composition between the upper and lower samples from Hongcan well implied the tectonic setting and property of the sediment provenance in Zoige Basin were altered obviously between late-period of Middle Triassic and mid-period or late-period of Late Triassic. This change was probably due to elevation and erosion of the matured continental crust on the east of Zoige Basin, and lots of clastic materials transported into the basin in late-period of Late Triassic.

通过对比杂砂岩稀土元素组成在上层和下层样品之间的变化，若尔盖盆地内中三叠世中期到晚三叠世中期及晚期沉积物源区的构造背景和性质发生了明显的改变，而这一变化很可能是盆地东侧成熟陆壳在晚三叠世后期被抬升和剥蚀，其大量碎屑物质被带到盆地的结果。

The present configuration of the rift, which dates from the mid-Pleistocene epoch, is probably a result of a rifting process associated with thermal currents in the earth's mantle elongated depression, trough, or graben in the earth's crust, bounded on both sides by normal faults and occurring on the continents or under the oceans.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
