... sulfide mineralization at Naica provide the first direct observations of main-stage fluids in these deposits. The inclusions can be divided into three compositionally distinct groups: (A) liquid + vapor (119 degrees -379 degrees C homogenization temperatures), (B) liquid + vapor + halite (237 degrees...
