The Shiyingtan gold deposit,located in a Late Paleozoic volcanic sequence along the northern margin of Tarim plate and western part of Kanggurtag metallogenic belt,was the first low-sulfidation epithermal gold deposit discovered in the eastern part of the Tianshan range,NW *** deposit is closely associated with an arcuate fracture system along the margins of a Permian *** mineralization is hosted in andesite,ignimbrites,and volcanic breccia with magmatic ages of ca.290-270 *** main orebodies,with a combined 200 000 oz Au resource,are composed of a series of steep,interconnected, crustiform-banded quartz veins,which together are as wide as 20 m and extend to depths of>200 *** gangue minerals in the ore-bearing veins consist of quartz,chalcedony,calcite,chlorite,adularia and sericite;metallic minerals mainly include pyrite,chalcopyrite,native gold,and *** temperatures and salinities of primary fluid inclusions in quartz vary from 130 to 250℃and from 0.8 to 6.7 wt%NaCl equiv.,*** and oxygen isotope data indicate that the mineralizing fluid was mainly of meteoric *** geologic and geochemical investigations confirm that the Shiyingtan gold deposit is a Late Paleozoic epithermal gold deposit of the adularia-sericite type.

Photo-grafting of hydrophilic monomer was used to enhance the hydrophilicity of poly（ether ether ketone）（PEEK） with the aim of extending its applications to biological fields. PEEK sheets were surface modified by grafting of acrylamide（AAm） with ultraviolet（UV） irradiation in the presence or absence of benzophenone（BP）. The effects of BP, irradiation time and monomer concentration on the surface wettability of PEEK were investigated. Characteriza tion of modified PEEK using scanning electron microscopy（SEM）, energy-disperse spectrometer（EDS） and water contact angle measurements shows that AAm was successfully grafted on PEEK surface both in presence and absence of BP. With the increase in irradiation time and monomer concentration, contact angles decrease to as low as 30°, demonstrating a significant improvement of surface hydrophilicity. In agreement with the decrease in contact angle, under identical conditions, the nitrogen concentration increases, suggesting the increase in grafting degree of the grafting polymerization. This investigation demonstrates a self-initiation of PEEK due to its BP-like structure in the backbone of the polymer. Though the graft polymerization proceeds more readily in the presence of BP, the self-initiated graft polymerization is clearly observed.

Stable thin films made from polyionic complex 2C12N+PVS- with incorporated Hb on PG electrodes were characterized by electrochemistry. The electron transfer between Hb and PG electrodes was greatly facilitated in microenvironment of 2C12N+PVS- films. The Hb-2C12N+PVS-films could be used to catalytically reduce trichloroacetic acid.
