Lanthanum vanadium epidote
Koox cilmi-baaris oo wadajir ah oo ka socda Jaamacadda Yamaguchi, Jaamacadda Ehime, iyo Jaamacadda Tokyo ee Japan ayaa soo saaray war-murtiyeed ay ku sheegeen inay heleen nooc cusub oo macdan ah oo ka kooban dhulyo naadir ah oo ku yaal Sanchong Prefecture.Dhul naadir ahCunsuriyadu waxay door muhiim ah ka ciyaaraan beddelka warshadaha soo jireenka ah iyo horumarinta qaybaha farsamada sare. Macdanta cusub ayaa laga helay buuraha Ise City, Sanchong Prefecture bishii Abriil 2011, waana nooc gaar ah oo epidote brown ah oo ka koobandhul dhif ah lanthanumiyo vanadium bir dhif ah. Bishii Maarso 1, 2013, macdantan waxaa loo aqoonsaday inay tahay macdan cusub Ururka Caalamiga ah ee Macdanta waxaana loo magacaabay "lanthanum vanadium limonite".
