The U-Pb and Pb-Pb isotopic dating of zircons provided the ages of 447-462Ma representing the ages of peak granulitic metamorphism. The U-Pb dating of detrital zircons from aluminum-rich gneisses yielded older upper intercept ages which reflect the times of older materials derived from sourse rocks of the gneiss protoliths.

岩石中变质锆石的U-Pb及Pb-Pb同位素测定获得447-462Ma的年龄值，代表其麻粒岩相的变质作用时代，富铝片麻岩中含继承组分的锆石还获得较老的上交点年龄，它可能代表其沉积岩原岩源区的年龄。

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.

对典型矿床不同富集标高矿体的化学全分析结果表明：随深度增加，Fe〓O〓、FeO、MgO及P〓O〓的含量有明显增高的趋势，这与赤铁矿化、绿泥石化及磷灰石化有关；-90m标高的CaO含量最高，达17.67％，反映这一部位的萤石化最发育；Na〓O及Na〓O+K〓O的含量由浅入深也存在明显的增高趋势，且Na〓O的含量在911m深处为最高，这充分显示碱交代作用从上到下有增强的趋势，而钠长石化在911m处最强烈。

The rbcL gene sequences of six species representing five subfamilies of the Hamamelidaceae and the Platanaceae were determined and used in the phylogenetic analysis on the "lower" Hamamelidae sensu Endress (1989) and its allies newly suggested.

测定了悬铃木科和金缕梅科5个亚科的6个代表种的rbcL基因序列，对低等金缕梅类植物及新近提出的相关类群进行了分子系统发育分析，获得4个最简约树。简约树步长为893，其CI值和RI值分别为0.558和0.591。

The newly collected DNA sequence data were analyzed with data collected in the previous studies involving species representing all the above families but the African Myrothamnaceae to address the phylogenetic questions of the"lower"Hamamelidae and the core family Hamamelidaceae.

主要结论包括：传统低等金缕梅类是一个复系类群；金缕梅科也是一个复系类群；ITS序列分析支持将连香树科包含在金缕梅科内，但是，rbcL资料和matK资料不支持将连香树科包含在金缕梅科内。
