Single zircon LAM-ICPMS U-Pb dating indi-cates that the Guidong granitic complex is a multistage ba-tholith formed during Indosinian-Yanshanian time. The Luxi body (239 ± 5 Ma) and the Xiazhuang body (235.8 ± 7.6 Ma) intruded during Indosinian time, whereas the Aizi body (160.1 ± 6.1 Ma) and the Siqian body (151 ± 11 Ma) formed during Yanshanian time. Inherited zircons (1275—2137 Ma) in the Xiazhuang body imply that at least part of the source rocks of the Guidong complex are from the Proterozoic basement of southeast China. Detailed single zirconLAM-ICPMS U-Pb dating results provide important evi-dence for understanding the evolution, tectonic setting andmineralisation of the complex.

Ca is a minor component of olivine (oliv). Its concentration measured by electron microprobe (EMP) is about 0.1—0.5%, which is close to the minimum detection limit. As Ca distribution between oliv and clinopyroxene (cpx)has the possibility of being used as geothermobarometers, it is very important to measure accurately the Ca content in oliv. Proton-induced X-ray emission (PIXE) technique as a new high energy analysis method shows advantage in high sensitivity and accuracy of microanalyses and begins to be

The genesis of intermediate-silicic intrusive rocks and their enclaves in Tongling are closely related to Fe, Cu mineralization, which may provide petrologic informa- tion on lithospheric dynamics in this region. Tongguanshan quartz diorite and its enclaves, representatives of the Meso- zoic intermediate-silicic intrusive rocks in the Tongling area, were studied using approaches of petrography, electron microprobe mineral chemistry and the LA-ICPMS zircon U-Pb dating. The chemical compositions of pyroxene and amphibole in pyroxene-amphibole cumulate, quartz-diorite host rock from Tongguanshan show correlative variations. The Al contents of the minerals in pyroxene-amphibole cu- mulate are higher than those in the host rocks, indicating that the cumulate crystals were crystallized before the em- placement of host magma. The consistent mineral chemical compositions between the Tongguanshan quartz diorite and the microgranular diorite enclave indicate that the enclave and host rock were crystallized under similar conditions and therefore are closely genetically related. The LA-ICPMS zircon U-Pb dating suggests that the crystallization age of Tongguanshan quartz diorite is 137.5±1.1 Ma, consistent with the previous dates by different methods. However, the present U-Pb dating also revealed the presence of late- Archean relict cores, demonstrating that older lower crustal materials were involved in the generation of Mesozoic mag- matic rocks in this area. Furthermore, the dating results show that the crystallization age of the microgranular diorite enclave is 137.5 ±2.4 Ma, the same as the crystallization age of the host magma. By integrating the previous Sr-Nd-Pb isotope data, it is also discussed the petrogenesis of quartz diorite and its enclaves in Tongguanshan.

Morphological and chemical studies on zircon grains from gabbro and granite of the Pingtan magmatic complex, Fujian Province, eastern China, show that there are three stages of zircon growth. The early stage of zircon growth is characterized by colorlessness, high transparence and birefringence, low and dispersive Ipr and Ipy, weak and homogeneous BSE brightness, lower Hf content and depletion of U, Th and Y; the middle stage is characterized by abruptly increasing lpy, progressively strong and sectoral-zoning BSE brightness, higher Hf content and enrichment of U, Th and Y with Th/U 〉 1; the late stage of growth is characterized by brownish color, poor transparence, low birefringence, highest Ipr and Ipy, middle and oscillatorily-zoning BSE brightness, highest contents of Hf, U and Y with Th/U 〈 1. The stages are considered to be formed in a deep magma chamber, ascent passage and emplacement site, respectively. Due to the more or less long residual time of the magma chamber, the difference in age between the early and late stages of zircon might be great enough to be distinguished, which can be attributed to tectonic constraint for the magnlatism.

雷州半岛英峰岭火山岩中单斜辉石巨晶以低Mg#值(0.62～0.47)、贫重稀土(HREE)和富Al2o3、Tio2、Na2o和中稀土(MREE)为特征,并具有明显的成分变化.随着Mg#降低,单斜辉石的Al2o3(11.58～6.97%)、Tio2(2.28～1.06%)和HREE逐渐降低.这种变化特征不同于世界上大多数辉石巨晶的变化规律.随着演化辉石巨晶的大多数不相容元素,如Nb、Sr、Zr、Hf和LREE-MREE逐渐增加.低的Mg#值和Ni、Co、Cr含量指示巨晶母岩浆是一种强烈演化的残余岩浆(Mg#=0.27～0.35).分离结晶模拟表明本研究最富镁的巨晶(Lz-54)的母岩浆很可能是由拉斑玄武质岩浆经70～80%以单斜辉石为主的结晶分异后形成.而本研究的其它辉石巨晶是该母岩浆在不同演化阶段(25～80%)分离结晶的产物.分离矿物中除了单斜辉石还包含了大量的石榴子石、斜长石和钛铁矿.温压计算表明英峰岭巨晶是高温岩浆在56～60km深的上地幔的结晶产物(T=1290℃～1130℃,P=1.73～1.83GPa),这一深度有利于石榴子石结晶.对比不同地区辉石巨晶的成分特征和形成条件,作者指出不同地区单斜辉石巨晶各种元素的不同变化规律主要受母岩浆成分和结晶条件控制.巨晶母岩浆在地幔结晶时对围岩橄榄岩进行了不同程度的交代作用.早期贫流体的岩浆对橄榄岩的交代作用较弱,只有Sr,La等强活动性元素被明显改变;晚期富流体(F,P,H2o)岩浆对橄榄岩的交代作用强烈,大多数元素被明显改变.因此,可以推断交代熔体中流体的含量是影响地幔橄榄岩交代作用的关键.
