Numerous investigations on submarine hydrothermal ore-forming occurrence have been actively carried out in the last two decades with significant results.The Ag and Au enrichments in the sulfides from black smokers ofhydrothermal vent field Broken Spur(MAR) aroused our interest to study their mineral hosting forms.Samples were collected from seven hydrothermal chimneys within Broken Spur in the British-Russian BRAVEX(1994) and Russian
