General Geology of Peramun Hill
Amongst the tourists attractions of Belitung is the rich variety of Granite boulders formed by structure of big boulders in harmony likes purposely built by human. In general those structures and granite boulders itself are strong even though there are obsolescence in some part of them.
Granite is a frozen rock originally came from magmatic material from eruption of volcano, usually formed a batholit which is giant frozen rocks with its dimention can be as mach as in kilometres range. Since it was form inside earth, the crystallisation process was slow and form a rough surface of the rock.
The granites that emerged at Peramun Hill, Tanjung Tinggi and Tanjung Kelayang form similar physical from by its bright color, including acid frozen rock with silicon contain above 66% as a result of magmatic process of granitic. The rocks in this area categorise Tanjung Pandan ( TrTg) granite formation and part of oldest plutonic that intrusive sediments during Trias era about 220-245 millions years ago (Baharuddin, sidarto, 1995, Peta Geologi Lembar Belitung).
The emerge of granite boulders to the ground surface can geologically explained from appearance of frozen granite boulders into the surface from kilomaters deep. It is categorised as frozen rocks that form a batholit. Caused by tectonic activities those materials suffered from elevation effect, and some suffer cracks and broken. As result of this tectonic process the underground granites then emerged into the earth surface. During the lifting up process, the granite form suffered from deformation form cracks and brooked. After very long process of millions of years the granite boulders appears as a separate boulders. Even though they were a solid form a large granite deep inside the earth before.
General Morphology of Peramun Hill
Morphology of Peramun Hill is based on form of natural field, slope of the hill and spread of rocks and formation of river flows. Based on those, Peramun Hill is a rough relief hill areas. This morphology unit forms a stiff surface of the hill. The slope of hillside usually about 17-30 degree ( 30-50 degree) and presence at the height of 110-150m above sea level. The river that flows form a rectangular and parallel flow that is permanent and some with periodic flows. It is formed by granite boulders of Tanjungpandan.
Peramun is a name of hill located at Selumar village, at district of Sijuk, Belitung regency. Peramun Hill is a tourist destination and conservation site managed by a community named ARSEL. There are many interesting attraction in this place such as the beauty of tropical forest, flora information, fauna and also the history and legend.
At the +90 meter above sea level there are two boulderd with almost equal size, likes placed by someone near one each other. These two boulders usually called twin rocks. The myth that related to these boulders are [anyone who can touch the two boulders by stretching thier two hands, for them who already have a family they will be given harmony and for anyone who still searching for couple will mett the love one soon].
