Secara administratif wilayah penelitian terletak di Desa Keramat dan sekitarnya, Kabupaten Boalemo, Provinsi Gorontalo. Daerah penelitian tersususun oleh batuan terobosan dari formasi Batuan Gabro (Teog), Formasi Batuan Granodiorit Bumbulan (Tpb) dan Formasi Aluvium (Qal). Kondisi geologi daerah penelitian sangat kompleks sehingga menarik diteliti karena belum pernah dilakukan penelitian secara detail. Tujuan penelitian yang akan dicapai adalah mengetahui karakteristik mineralogi dan tekstur serta proses terbentuknya batuan dasar berdasarkan data pemetaan geologi dan data petrografi. Metode penelitian yang digunakan untuk mencapai tujuan penelitian tersebut terdiri dari survei geologi lapangan, penelitian laboratorium, dan pengolahan studio. Metode observasi lapangan adalah metode yang berfokus pada pengamatan kondisi geologi di daerah penelitian. Kemudian data-data yang diperoleh dianalisis menggunakan metode penelitian laboratorium berupa analisis petrografi dengan sayatan tipis. Hasil penelitian menunjukkan bahwa Morfologi daerah penelitian terbagi menjadi 2 satuan yaitu satuan perbukitan rendah struktural dan dataran aluvial. Stratigrafi daerah penelitian dibagi menjadi 2 satuan diurutkan dari tua ke muda yaitu satuan gabro, satuan granodiorite dan satuan endapan aluvial. Struktur geologi yang bekerja pada daerah penelitian berupa kekar gerus yang memiliki arah barat laut-tenggara hingga timur laut-barat daya. Berdasarkan hasil analisis petrografi yang telah dilakukan maka diperoleh hasil karateristik batuan gabro sebagai batuan dasar pada formasi gabro adalah berwarna putih kecokelatan (PPl), berwarna abu-abu hingga orange (XPL), hypokristalin, ukuran kristal (1-3 mm), bentuk dan hubungan antar kristal subhedral. Tekstur umum ekuigranular faneritik dengan komposisi mineral penyusun batuan yaitu plagioklas, K-feldspar, biotit, piroksen, mineral opak dan mineral alterasi penyusun batuan serisit. Batuan ini merupakan bagian dari jalur magmatisme pada zaman Eosen.
