ABSTRAK

Gunung Stong terletak di dalam unit batuan yang dikenali sebagai Kompleks Stong. Kompleks Stong ini terdiri daripada tiga unit suit batuan dikenali sebagai Suit Berangkat, Suit Kenerong dan Suit Noring. Suit Berangkat boleh dibahagikan kepada tiga unit litodemik, iaitu litodemik Granit Sungai Lah, Granodiorit Bertam dan Tonalit Dabong, manakala Suit Kenerong mengandungi litodemik Leukogranit Stong dan Migmatit Sg Kenerong. Bagi Suit Noring pula, ia dibahagikan kepada Granit Sungai Long, Granit Sungai Suda dan Mikrogranit Sungai Terang. Selain itu, batuan keliling juga tersingkap terdiri daripada batuan metasedimen dan sisa kubah hasil terobosan pluton. Penamaan di lapangan dan kajian secara petrografi menunjukkan terdapat 10 jenis batuan igneus iaitu terdiri daripada monzonit hingga monzonit kuarza, granit hornblend dan granit biotit bertekstur porfiri dan granit biotit tekstur sama saiz butiran hingga mikrogranit, granodiorit dan tonalit. Seterusnya, terdapat juga selang lapis batuan metasedimen yang termetamorf membentuk syis biotit muskovit, syis hornblend dan syis garnet. Kepelbagaian jenis batuan ini adalah unik dan boleh dijadikan satu sumber geowarisan untuk mengiktiraf Kompleks Stong kepada Geotaman di Kelantan.

ABSTRACT

Stong Mount is located within the rock unit known as Stong Complex. The Stong Complex consists of three suite rock units whiz the Berangkat Suite, Kenerong Suite and Noring Suite. The Berangkat Suite can be divide into three litodemics unit called as Sungai Lah Granite, Bertam Granodiorite and Dabong Tonalite, whereas the Kenerong Suite consists of Stong Leucogranite and Sg Kenerong Migmatite. For Noring Suite, it was divided into Sungai Long Granite, Sungai Suda Granite and Sungai Terang Microgranite. In addition, the country rock was also covered by metasedimentary rock and roof pendant as a result from plutonic intrusion. Naming in the field and petrographic study show that the igneous rocks can be classified into 10 types such as monzonite to quartz monzonite, hornblend granite and biotite granite with phorpyritic texture and isogranular biotite granite to microgranite, granodiorite and tonalite. Futhermore, there was an occurrences of metamorphosed interbedded sedimentary rocks forming a biotite muscovite schist, hornblend schist and garnet schist. The variety of rock type is unique and can be establish as geoheritage sources to nominate Stong Complex as Kelantan Geopark.
