rgds, seno "miko" <[email protected]> 03/17/2009 09:12 AM To <[email protected]> cc <[email protected]> Subject Re: Laurit Mineral Yth Pak Wahyu, Mohon maaf, mang Okim lemparkan pertanyaan Pak Wahyu ke forum IAGI agar rekan-rekan yang lebih kompeten khususnya komandan Divisi Sumber Daya Mineral PP-IAGI Pak Hadianto atau Pak Yatno, atau yang lainnya dapat menjawabnya dengan lebih lengkap ( menyangkut genesa, lingkungan geologi, kegunaan, nilai ekonomi, pemasaran, etc ). Sementara menunggu penjelasan rekan-rekan, mang Okim sampaikan uraian tentang mineral Laurit ini sesuai dengan yang tercantum di buku Glossary of Geology dari Bates and Jackson ( American Geological Institute Alexandria, Virginia, 1987 ) : Laurite : An iron-black mineral ( RuS2 ) . It often contains osmium. Laurite is found in association with platinum in placer deposits and usually occurs in minute octahedrons resembling those of magnitite. Nah, karena penjelasan Bates and Jackson di atas tidak menyinggung tentang Laurite primer dll. nya, maka diharapkan rekan-rekan dapat melengkapinya. Sekedar masukan untuk Pak Wahyu, mempertimbangkan bahwa asosiasinya dengan platinum, maka seharusnya yang dikejar bukan Laurite nya melainkan ya itu, Platinumnya - - - ta' iya - - - !!!

Pak Miko Saya mendapat pertanyaan dari teman dosen teknik sipil tentang mineral Laurit (RuS2) yang merupakan endapan placer di Kalimantan, dengan type locality di Sungai Pontin, Tanah Laut dan Sungai Tambanio, Kalimantan. Apakah Pak Miko punya info tentang mineral ini dan penjelasan geologinya? sepertinya mineral ini sangat jarang ditemui atau mineral jarang, dan menurut paper mineral ini ditemui di batuan beku yang ultramafic - mafic. Demikian pertanyaan saya, maturnuwun buat penjelasannya. regards, Wahyu Seno Aji The information contained in this communication is intended solely for the use of the individual or entity to whom it is addressed and others authorized to receive it.
