This area include to Merangin Geopark, where the Mengkarang River had characteristics of rock ages 290 million years and intruded by 200 million years Granite. There also found fossils like Calamites sp., preserved Log Fossil, ancient Root and some kinds of fossils such as Pecopteris sp., Gigantopteris sp., and Cordadites sp., thus this area known as endemic area and marker of ancient flora fossils which has older age than the other region. It also found a cascading waterfall as result of fairly structural control. Geologically, this area include in Mengkarang Formation age as Paleozoic’s Permian, older than the ages of basins in Sumatra Island, and intruded by Jura’s Granite.

There also found fossils like Calamites sp., preserved Log Fossil, ancient Root and some kinds of fossils such as Pecopteris sp., Gigantopteris sp., and Cordadites sp., thus this area known as endemic area and marker of ancient flora fossils which has older age than the other region. It also found a cascading waterfall as result of fairly structural control. Geologically, this area include in Mengkarang Formation age as Paleozoic’s Permian, older than the ages of basins in Sumatra Island, and intruded by Jura’s Granite. Morphologically, Mengkarang River surrounded by eroded hills, create the hidden impression and cause the river preserved well. The river condition, which is not too deep, facillitate the tracking alongside the river and the banks of river, while learning the characteristic of Mengkarang Formation plentiful of endemic fossil of flora and fauna. Geotourism potential here beside have a geological value, also have cultural value which based on local community aspect and support for the development of the area.

Adapun tujuan dari paper ini untuk memberikan masukan serta pentahapan dari interpretasi struktur geologi secara sistematis guna mempermudah dalam mengetahui geologi dari suatu wilayah. Data-data yang dapat membantu dalam interpretasi antara lain data citra seperti LIDAR dengan menggunakan metode MDCA (Multi Criteria Desicion Analysis, yang mana mempertimbangkan pola pengaliran yang berlaku di daerah tersebut. Lalu pada data singkapan, dilakukan rekonstruksi dengan metode 2D maupun 3D yang mana menggunakan prinsip stratigrafi antarsatuan batuan sebelum terdeformasi. Kemudian apabila diperlukan, data batuan yang mengalami deformasi struktur geologi dengan analisis berupa petrografi guna mendapatkan besar-kecilnya deformasi yang telah terjadi di daerah tersebut. Lalu kesemua data dijadikan acuan dan memiliki keterkaitan, sehingga persentase akurasi dalam interpretasi geologi akan semakin besar.

One of the parts of this basin is the Palembang Group and Telisa Group, which can be observed its contacts in the area Sukomoro, South Sumatra, Indonesia. Thus, it is important to analyse the stratigraphy data of the Sukomoro Village in the determination its Paleoclimate and Paleogeography, in order to determine how much its progress and relation to the current ecosystem conditions. Based by data in the form of outcrops, rock samples, and measurement data either in the field or in the studio, it observed that the location's type of deposition process was Transgression. Based on the Paleoclimate, it observed when the deposit of Telisa Group the Earth's climate was warming know from the transgression views of stratigraphy observed at Telisa Group Talangakar Formation and the contact with Gumai Formation. Paleogeographic of Sukomoro Village, South Sumatra, Indonesia is a coastal area with a typical transitional deposit with tidal environment.
