THE TRANSITION MINERALS COPIAPITE AND COQUIMBITE Many geologists
are familiar with the formation of golden-yellow copiapite in abundance as a
transitional mineral between pyrite and limonite where seams of semi-massive or

Owing to the fine grain of the mineral the refractive indices are known only to lie
between 1.75 and 1.79, and thus compare favorably with the indices of
carphosiderite (0 : 1.82, E: 1.73) ; the indices of coquimbite are 0: 1.53 and E :
1.57. Also ...
