Recent developments in the research on the geology and geochemistry of the newly-discovered clayey breccias at the lop of the Xiaochaka Formation in the Juhuashan, Xiaochaka and Shishuihe areas, Qiangtang Basin, northern Tibet have disclosed that mineral compositions, textures and structures, occurrences and sectional architectures of the clayey breccias agree well with those of the paleo-weathering crust in these areas. Compared with the bedrocks, the paleo-weathering crust is characterized by the leaching out of CaO and CO2, and relative enrichment of SiO2, Al2 O3, Fe2O3, K2O, Na2O, MnO and P2O5. The clayey weathered residues in the paleo-weathering crust are characterized by marked enrichment of REEs, much higher contents of LREEs than those of HREEs, markedly positive Ce anomalies and negative Eu anomalies, and a noticeable increase in other element contents besides Mo, Sn and U from the clayey weathered residues.

对最近在藏北羌塘盆地菊花山、肖茶卡、石水河等地区新发现的肖茶卡组顶部的粘土质角砾岩的地质、地球化学特征研究表明：其岩石矿物成分、结构构造、角砾层产状及剖面演化序列等与古风化壳的形成及其特征较为一致；相对于基岩，古风化壳的主量元素表现为CaO、CO2的淋失和SiO2、Al2O3、Fe2O3、K2O、Na2O、MnO、P2O5等不同程度的相对富集；古风化壳中的粘土质风化残积层的稀土元素具有明显的富集，表现为LREE含量远大于HREE的特征，存在明显的Ce的正异常以及Eu的负异常；微量元素除Mo、Sn和U外，粘土质风化残积层的其余元素含量均有明显的增加。

Apps designed specifically for the iPad get good review s, particularly Marvel Comics, which Boing Boing describes as 'game changing,' and an app about the periodic table of the elements, which might not sound interesting but which is apparently 'dazzling' and 'not like any e-book you've seen,' according to Boing Boing and USA Today.
