| Abstract: | The orebody of Toma firebrick shale deposit in Ludian,Yunnan is bedded,stratoid in Uppe P XuanweiFormation(P3x).The orebody extension is stable,occurrence is consistent to the strata,contolled clear by the horizon,belngngto the land lake facies sedimentary ore deposit.Upper P uanwei Formation is the specific prospecting horizon and the important criterion is the stable purple tuffaceous shale of orebody bottom. |
