The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others. Since the areas yield pyrite with relatively lower contents of main components S and Fe, while a greater gross content of trace elements, such as Cu, Pb, Zn, Au, Ag, are closely associated with gold deposits, the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area; and there is a remote possibility to find a large gold deposit in Shengjingao area, wih a prospect of finding a concomitant gold deposit.gold deposits;mineralogical.

对某高泥化高氧化铁锰黑土矿中的金进行了试验研究，试验采用黄铁矿作为载体有效回收了黑土矿中的金，并对载体浮选的几个主要条件进行了对比，结果表明用磺化煤油作辅助捕收剂可增加细粒金的回收，同时也降低了黄药和2#油的用

It is considered that the source of minerals etc mainly comes from the pyritization sources of the submarine volcano eruption.

认为含矿岩系的物源主要来自海底火山喷发作用形成的黄铁矿化矿源层。

陕南埃迪卡拉纪晚期的高家山生物群中部分化石以黄铁矿化三维立体保存软躯体管状化石为主要特征。

Pyritization occurred commonly in spicules, which could play an important role for the preservation of the spicules. The Hetang sponge spicules indicate that the hexactinellids and demonsponges evolved on later than the Meishucunian-Qiongzhusian (Tommotian - Atdabanian) time.

黄铁矿化在化石的保存中起了重要的作用，化石产出的时代可能为梅树村阶至筇竹寺阶(Tommotian-Atdabanian)，这个化石组合证实了海绵动物在早寒武世已开始迅速分异。

In this paper, the authors found the pyritized rod-like bacteria in desmocollinite and the Cyanophytes's gelationous sheath and the degraded organic matter of blue green algae in collinite of high-sulfur coal seams No.9 w(So=2.67% and No.10 w(So=2.54% using SEM-EDX and TEM. These findings of bacteria and algae suggest that they play an important role in the high-sulfur formation.

应用带能谱仪的扫描电镜和透射电镜，在乌达矿区高硫煤9煤层和10煤层的基质镜质体中发现了黄铁矿化的杆状菌落，在无结构镜质体中发现了蓝藻胶鞘及其降解有机质，这些菌藻类体的发现表明低等生源在高硫煤形成过程中起了重要作用。

In the space, along with increased distance from the main ore-controlling structures, the frequency of P type of pyrite and their thermoelectricity also decreased gradually. Within one lode, from the upper to the lower parts of an ore body, the vertical change of pyrite in thermoelectricity as the follows:① when the ore body is stable, that is when the ore body is uniformly and continuously mineralized, the Dp andαvalues keep increased from shallow to deeper parts;② when an ore body is discontinuously mineralized, the Dp andαvalues have a wavy increasing tendency from the shallow to the deeper;③ when the deeper part of an ore body contains abundant, Co and Ni high mafic dykes, the Dp andαvalues of pyrite decreased from the shallow to the deeper parts of an ore body, that is, an reversed zoning of pyrite thermoelectricity occurs for pyrite in this situation contain more Ni and Co and belongs to N type.④ For the deposits hosted in the Archean metamorphic rocks, because all of the pyrite in this case is N-type, the vertical change of pyrite is not featured by the transition of pyrite type, but by the increased values of Vnp and α from the shallow to deeper parts of an ore body.

在空间域上，水平分带规律为：随远离主干断裂，矿脉中P型的出现频率逐渐降低或热电系数值逐渐变小；在同一条矿脉中，这是由于矿化不均匀性及脉岩的影响，由矿体的上部到下部，它的垂向变化特征可以有如下几种变化形式：①由矿体的浅部到深部，黄铁矿的Dp值、或α值呈稳定升高的趋势时，矿体往往表现为矿化均匀，连续性好、延伸稳定；②由浅部到深部，黄铁矿的Dp值、α值呈波状变化，但总体又具有增大的趋势时，所在的矿体连续性差；③当矿脉的下部发育有大量的基性脉岩时，由于基性脉岩中常含有较高的Co、Ni，使其中黄铁矿的Co、Ni含量较高而呈N型导电，由矿体的上部到下部，黄铁矿的Dp值、α值呈减少的趋势，而造成黄铁矿热电性特征的逆向分带，④产于太古代变质岩中的中深脉状金矿，由于其中的黄铁矿均为N型导电，所以垂向变化规律并不表现为导型的改变，只是Vnp值或α值从矿体的上部到下部由小变大。
