APAKAH MAKSUD RUBIDIUM-STRONTIUM DATING dalam CORSICA?
Dating Rubidium-strontium
Kaedah dating rubidium-strontium adalah teknik temu radiometrik yang digunakan oleh para saintis untuk menentukan usia batu dan mineral dari kuantiti yang mereka mengandungi isotop spesifik rubidium dan strontium. Perkembangan proses ini dibantu oleh ahli kimia Jerman, Otto Hahn dan Fritz Strassmann, yang kemudiannya meneroka pembelahan nuklear pada bulan Disember 1938. Penggunaan sistem isotop rubidium-strontium dari fakta bahawa 87Rb mereput kepada 87Sr dengan separuh hayat 48.8 bilion tahun. Di samping itu, Rb adalah unsur yang sangat tidak serasi yang, semasa proses penghabluran kristal pecahan, kekal di cair magmatic daripada menjadi sebahagian daripada galian mantel. Anak perempuan radiogenik, 87Sr, dihasilkan dalam proses pembusukan ini dan dihasilkan dalam pusingan nukleosintesis cemerlang yang menimbulkan penciptaan Sistem Suria. Mineral yang berlainan dalam keadaan geologi yang diberikan dapat memperoleh nisbah strontium-87 radiogenik yang tersendiri untuk secara semula jadi ...
Definisi rubidium-strontium dating dalam kamus Corsica
Takrif rubidium-strontium bertarikh dalam kamus adalah teknik untuk menentukan umur mineral berdasarkan kejadian rubidium semulajadi dari jumlah tetap radioisotope 87Rb yang mereput ke strontium isotop 87Sr dengan separuh hayat 4.7 × 1011 tahun. Pengukuran nisbah isotop-isotop ini memberikan umur mineral, untuk umur sehingga kira-kira 4 × 109 tahun.
