APA TEGESÉ RUBIDIUM-STRONTIUM DATING ING BASA INGGRIS?
Kencan Rubidium-strontium
Cara tetandhuran rubidium-strontium yaiku teknik gendakan radiometrik sing digunakake dening para ilmuwan kanggo nemtokake umur batune lan mineral saka jumlah sing diasilake saka isotop spesifik rubidium lan strontium. Perkembangan proses iki dibantu dening ahli kimia Jerman Otto Hahn lan Fritz Strassmann, sing nuli mbuka fisi nuklir ing Desember 1938. Utawa sistem isotop rubidium-strontium nyebabake kasunyatan sing 87Rb ilang nganti 87Sr kanthi umur setengah 48,8 milyar taun. Kajaba iku, Rb minangka unsur sing paling ora kompatibel sing, nalika kristalisasi fractional lapisan, tetep ing leleh magmatic tinimbang dadi bagean saka lapisan mineral. Putri radiogenic, 87Sr, diprodhuksi sajroning proses pembusukan iki lan diprodhuksi sajroning nukleosintesis lintang sing ngetokake penciptaan Tata Surya. Mineral sing beda-beda ing panggunaan geologic tartamtu bisa ndarbeni rasio strontium-87 radiogenik sing béda kanthi alami ...
Definisi saka rubidium-strontium dating ing bausastra Basa Inggris
Definisi rubidium-strontium dating ing kamus punika teknik kanggo nemtokake umur mineral adhedhasar kedadeyan ing rubidium alami saka jumlah radioisotope 87Rb sing tetep kanggo strontium isotop 87Sr stabil kanthi umur setengah saka 4,7 × 1011 taun. Pangukuran rasio isotop-isotop iki saingga menehi umur mineral, kanggo umur nganti kira-kira 4 × 109 taun.
