本文对甘肃北山地区肃北县南金山金矿床的成矿年代学和成矿流体进行了系统研究。40Ar-39Ar同位素测年结果表明，南金山金矿石中绢云母的40Ar/39Ar坪年龄为242.8±0.8Ma，相当于印支早期，略晚于南金山金矿床附近闪长岩中黑云母的40Ar/39Ar坪年龄(244.2±0.3Ma)，这表明印支早期闪长岩对南金山金矿床的形成起着重要的控制作用。

It is mainly in submicro particles adsorbed at the crystal rims of clay mineral kaolinite and illite,or in micro particles included within limonite,little amount of gold is in the adsorbed phase of limonite.

研究表明，这些金以超显微金的形式存在于粘土矿物高岭石、水云母的晶体边缘，或混杂于褐铁矿中的针铁矿晶体集合体之间，少数呈褐铁矿的吸附相形式存在。

In this research project, we have got a series conclusions:(1) there is no excess argon in the high-pressure white micas being in the orthogneiss;(2) The distribution of excess argon in eclogite is positive correlative with the ratio of Mg/, but negative with the ratio of Na/;(3) The in-situ analyses by using the method of laser probe 39Ar-40Ar show that the age radius from central to margin in a single grain of high-pressure white mica in eclogite;(4) There is no any evidence to prove that the excess argon in eclogite comes from fluid;(5) The excess argon in eclogite inherited from primitive rock during high-ultra high pressure metamorphism;(6) There is no excess argon in the eclogite when its surrounding rock is carbonate.

本项目用综合手段，研究了高压白云母中过剩氩的来源、赋存、分布与岩性、产状、矿物元素和矿物显微结构之间的相关关系，以确定过剩氩在高压白云母中赋存的主要控制因素。初步得出了以下结果：1、高压变质的正片麻岩中的白云母中不含过剩氩；2、高压白云母中过剩氩的赋存和Mg/有着正相关关系，而和Na/呈负相关；3、激光微区氩-氩分析表明，榴辉岩中的单颗粒多硅白云母存在年龄梯度；4、初步否定了高压白云母中过剩氩来自于流体的说法；5、初步认定，榴辉岩中多硅白云母中过剩氩主要是在高压-超高压变质过程中由内部继承的；6、在阿尔金及柴北缘等地围岩为碳酸岩的榴辉岩中的高压白云母不含过剩氩。上述研究结果将推动过剩氩成因研究走向深入。

Based on the Re-Os isochron method of molybdenites, this paper measured directly the ore-forming age from skarn ore in the Huangshaping deposit, and got a Re-Os age of (153.8±4.8)Ma, which is in accordance with the previous K-Ar age of 153~157 Ma obtained from phlogopite in the ore-bearing skarn of the deposit.

文章采用高精度的辉钼矿Re-Os等时线定年法，直接测得硅卡岩型矿体的矿化年龄为(153.8±4.8)Ma，与前人获得的含矿硅卡岩中金云母的K-Ar年龄(153~157Ma)一致。

We can offer three types of this mica tape, they're HY450-5 Silicone Glass Phlogopite Mica Paper Tape, HY460-5 Silicone Glass Phlogopite Mica Paper Tape (low binder content, reinfored only on surface), HY460-5S Silicone Glass Phlogopite Mica Paper Tape.

The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.

研究发现我国白云母主要产地的大片白云母均为普通白云母，变质岩地区的碎白云母以多硅白云母为主；本文研究的印度的大片白云母、碎白云母均为普通白云母；印度白云母基片的表面活性高于我国白云母；酸处理容易沿平行于白云母基面的方向侵蚀，虽未使白云母晶体结构产生破坏，但造成了白云母热稳定性降低。

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。
