APAKAH MAKSUD LAMPROPHYRE dalam CORSICA?
Lamprophyre
Lamprophyres (Yunani λαμπρός (lamprós) = "terang" dan φύρω (phýro) = untuk campuran) adalah jarang berlaku, bebatuan kecil bit ignitud ultrapotassic terutamanya berlaku sebagai dikes, lopoliths, laccoliths, stok dan gangguan kecil. Mereka adalah batu mafic silica-undersaturated atau ultramafic dengan magnesium oksida tinggi, \u0026 gt; 3% kalium oksida, natrium oksida tinggi dan nikel dan kromium tinggi. Lamprophyres berlaku sepanjang zaman geologi. Contoh Archaean biasanya dikaitkan dengan deposit logam emas. Contoh-contoh cenozoik termasuk batu magnesia di Mexico dan Amerika Selatan, dan lamprophyres ultramafic muda dari Gympie di Australia dengan 18.5% MgO pada ~ 250 Ma.
Definisi lamprophyre dalam kamus Corsica
Takrif lamprophyre dalam kamus adalah mana-mana sekumpulan batuan igneus asas yang terdiri daripada feldspathoids dan mineral ferromagnesian, esp biotite: yang berlaku sebagai dykes dan pencerobohan kecil.
