GEOLOGY AND HEAVY MINERAL ANALYSIS OF LOOSE SAND FROM AUKZEIK AREA, THE KALEKOK ISLAND, LAMING SUB-TOWNSHIP, MON STATE
Abstract
- Heavy mineral analysis was systematically carried out mainly focus on the beach sand of the Kalekok island. It is situated about 144km south of Mawlamyine and about 35 km north of Ye township, Mon State. It lies between latitude N 1529′00″ to 1532′ 30″ and longitude E 97 38′30.00″ to 97 40′ 15.00″ in one inch Topographic Map no.95 E/10. The topographic features of the whole area are generally mountainous and the drainage pattern show medium to coarse texture, subparallel pattern. The igneous rocks are microdiorite, hornblende biotite granodiorite with microdiorite xenoliths, biotite granite and leucogranite. The probable age of the igneous rocks may be emplaced in Early Cretaceous. The study area falls in tropical monsoonal climate and the annual rain fall is 99.83". The maximum temperature is 36.2˚C and the minimum temperature is 20.14˚C. The wind speed lies between 6 to 25 mph and most of wind direction is SW, E and SE directions. The XRF assay results and average heavy mineral data of the research area related to the silicic igneous origin, related to high rank metamorphism and the deposition through Triassic to Miocene. Titanium, zirconium, ilmenite, monazite, magnetite, REEs and radioactive elements are commonly occurred. These minerals are very important for industrial purposes and economical point of view. This research is supporting for the genesis of heavy minerals and related rocks, to get foreign income of the country, to explore the ore mineral resources, to development of industrial zone, to get the opportunities of employment for the local people, to maintain and reduce the damage of the coastal’s natural environment.
