In addition, dacite porphyry injected into the lower part of the Huanghuashan breccia is dated by using the 40Ar/39Ar method, which has a plateau age of 122.1± 0.3Ma and an isochrone age of 121.8 ±1.4Ma.

It did not grow up spontaneously in the Middle Ages; it was bequeathed in a text of porphyry's "Isagoge", a text that seemed simple and innocent, though somewhat obscure, but one which force of circumstances made the necessary starting-point of the earliest medieval speculations about the Universals.

它没有长大自发在中世纪,它留下的文字斑岩的" Isagoge "的文字,似乎简单,无辜的,尽管有些模糊,但这种力量的情况下作出必要的起点最早的中世纪猜测的共性。

His Logic is divided into nine parts, of which the first is an introduction after the manner of Porphyry's "Isagoge"; then follow the six parts corresponding to the six treatises composing the "Organon"; the eighth and ninth parts consists respectively of treatises on rhetoric and poetry.

他的逻辑是,分为九个部分,其中第一个是引进后的方式斑岩的" isagoge ",然后沿着共分六个部分,相对应的六个论文撰写的"欧加农";第八和第九部分组成,分别就论文修辞学和诗歌。

This debate on universals, found in Porphyry's Isagogue, caused great controversy during the Middle Ages.

Fluorites formed in uranium mineralization period in the Zoujiashan and Shazhou uranium deposits have ε〓 values from -6.7 to -8.3 and I〓 values from 0.7145 to 0.7204, similar to their host rocks (porphyroblastic lava and sub-granodioritic porphyry) which have ε〓 values from -6.2 to -9.4 and I〓 values from 0.7121~0.7192. On diagram of ε〓- t, the fluorites and host rocks plot in similar area within the evolution field of the basement rocks at Xiangshan. The lead isotopic compositions of pyrites formed in uranium mineralization period plot as a line on diagram of 〓Pb/〓Pb vs.〓Pb/〓Pb. The host rocks plot at the lower value end. Calculation based on the slope of the line and the mineralzation age yields age of 144Ma for the geological body which provided uranium for the mineralization.

邹家山和沙洲铀矿床成矿期萤石的ε〓值(-6.7~-8.3)和I〓值(0.7145~0.7204)与赋矿围岩(碎斑熔岩及次花岗闪长斑岩)的ε〓值(-6.2~-9.4)和I〓值(0.7121~0.7192)相似,在ε〓-t图上,成矿期萤石数据点的投影范围与赋矿围岩的基本吻合,且均落在相山元古宙基底演化域范围内;成矿期黄铁矿的铅同位素组成在〓Pb/〓Pb-〓Pb/〓Pb关系图上呈线性分布,而火山岩的铅同位素组成位于此相关线的低值一端;利用异常铅线的斜率及成矿年龄计算出富铀地质体的形成年龄为144Ma,这与赋矿围岩的成岩年龄(135~140Ma)非常接近。

Pb-Sr-Nd isotope tracing shows that the source of magma in the island-arc belt of Zhongdian area belongs to crust-mantle mixed type. The proportion of mantle material is 59.5% crust's is 40.5%. Similarly, for the Cenozoic alkaline-enriched porphyries, the source of magma is crust-mantle mixed type, but the proportion of mantle material is increased to 54.3%.

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世;浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma,这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。
