The present study area covers the northwestern part of Kachin State including Putao Township. The pronirnent geographic feature of this area is the Mount Phongumrazi which is about (10500) feet height above sea level with snow caps in all seasons. This area is geologically still unknown and systematic geological investigation had never been studied yet. The study area is composed ofmostly Igneous and Metamorphic rocks. The igneous rocks are biotite granite, hornblende biotite granite, peridotite and hornblendite. They are frequently cross cut by pegmatite, aplite veins and silica veins in numerous places. Most of these are found as massive and boulder in shape, and their sizes are very large amount to form as elevated mountain ranges distributing Putao township. The metamorphic rocks are intruded by igneous rocks. They are hornblende biotite gneiss, marble and hornblende biotite schist and garnet mica schist. They are shown as south plunging anticline structure in regional scale. The sedimentary rocks are found as Putao gravel and alluvium which are only observed at only Putao and neighbouring area. As economic point of view some Putao Jade (Grossular garnet) occurrence near upper Shangaung village, ruby and sapphire occurrences at Manse Kaung village and small scale placer gold mines are done by local people in numerous streams banks particularly at lower Shangaung areas .Granite are also used for road and construction materials and marble can be applied for raw material ofcement industry. Key words: Granite in Northern Myanmar, Phongumrazi region, Putao Jade and Placer gold. Introduction Kachin State is located in the northern part of Myanmar between India to the west and China to the east and north. The present study area covers the northwestern part of Kachin State including in Putao Township. (Fig. I). The prominent geographic feature of this area is the Mount Phongumrazi which is about (10500) feet height above sea level with snow caps in all seasons. It is composed ofhighly mountainous regions which are 1. Pro-Rector, Dagon University 2.

This atea is geologically still unknown and systematic geological investigation had never been studied yet. Therefore, the geological investigation is also required to prepare geological map of study area with fairly detailed and to record the possible mineralization and mineral resources.

Fig, (1) Location Map ofthe Putao Area Universities Research JoumaI2008, Vol. I, No.2 3 This paper is one ofthe outcomes ofthe Phongumrazi Expedition of Myitkyina University which is an -interdisciplinary and integrated approach on the combination studies of Botany, Zoology, Geology and Geography departments. This paper is an attempt to fill up a gap ofgeology knowledge ofthe northern Myanmar and its mineral resources. The present area. covering part of 92 E-SE & NW of half-inch topographic maps, lies in the NW of Putao township. This area lying between Lat. N 27" 15'-27" 35' and Long. E 97°10' E-97 30' is bounded by the Malikha river in the east and the boarder line of Myanmar and India in the west. Due to the extensively dense vegetation and very rugged terrain, field traverses
