Mineralogy and Geochemistry of Palung Granite Massif

Palung massif which has a sharp contact with the country rocks, is one of those six granitic bodies that are situated in the Mahabharat Range of Central Nepal. This massif is a multiphase intrusive containing a number of facies rock varieties. The most widely distributed facies are coarse grained inequigranular porphyritic tourmaline granites in the central part and inequigranular tourmaline granites with portions of micropegmatitic texture in the apical part. Mineralogical and geochemical studies reveal that these granites are probably leucocratic differentiate of palingenetic granitic magma.

Kali Gandaki gravel deposits of central West Nepal — their neotectonic significance

The terraced gravel deposits of the Baglung-Behadi region in the Kali Gandaki valley, central West Nepal, reveal geomorphic features related to neotectonism. The accumulation of thick fluvioglacial gravel deposits in lake-like basins along the then existing river course took place due to the uplift of the southern Mahabharat Range and the relative subsidence of the Midland. The deposits consist of unsorted fragments of variable size, showing considerable uniformity laterally over large areas from north to south, and with abundant angular to sub-rounded boulders of Dhaulagiri limestone and gneisses of the Main Central Crystallines. Terrace flats arranged in three successive levels on either side of Kali Gandaki show that the region has undergone at least three periods of uplift.

Ecological Distribution of <i>Cyclemys oldhamii</i> (Gray, 1863) from Nepal

Tangting River originates from southern slope of Murtidanda of Mahabharat range and forms a very narrow v-shaped agriculturally fertile valley in lower parts of Chure hills. It has three main tributaries merging from east and west. Water is clear with rocky bed and margin is covered with thick bushes of semi-shrubs (Eupatorium adenophorum). During the herpetological survey, a live juvenile specimen of Cyclemys oldhamii (Gray, 1983) was collected from the periphery of Banmare Khola, an eastern tributory of the river. It was found hiding in the paddy field in the flood plain of Tangting river (280 m), and another adult specimen was collected from Dhobi Khola (450 m), a western tributory of the river. Empty shells were also collected from Garuwa and Mai valleys, respectively. Tangting and Garuwa river valleys are the favourable habitats for Cyclemys oldhamii. The main reason of discontinued distribution is habitat loss by deforestation. Key words: Cyclemys, Morphology, Ecological habitats, Distributiondoi:10.3126/on.v2i1.317Our Nature (2004) 2: 7-12
