| The various datolite-bearing lodes are described stratigraphically from the uppermost to the lowermost lode in the series. |
|
| Two mining companies attempted to exploit the copper lodes at different times, and both ventures ended in failure. |
|
| This particular color has not been found in other lodes in Ontonagon County and distinguishes datolites from this locality. |
|
| Copper also filled voids and occurred in thin fissure veins that cut the lodes. |
|
| Porcelaneous datolite occurred in the amygdaloidal lodes as veins, vesicle filling, and nodules. |
|
| The rock layers surrounding coal lodes were penetrated and separated by drillers and explosives. |
|
| Edward Baldwin's upstate New York roots were identified by the Oneida, Mohawk, Mohican, and Iroquois lodes. |
|
| It can be found in fissure veins and brecciated amygdaloidal basalt lodes but not in the conglomerate lodes. |
|
| Marketing samples, for example, can be rich lodes of new failure types because these units are often the first to leave the engineering lab. |
|
| The Butler, Evergreen, and Knowlton lodes were explored and mined to some extent. |
|
| Many miners named their lodes for places from which they had emigrated. |
|
| Mineralogically, the conglomerate lodes have produced many superb specimens, although they contain fewer mineral species than the fissure veins and amygdaloidal lodes. |
|
| Most of the minerals present in the conglomerate lodes belong to the same general period of copper mineralization that occurred in all the native copper deposits. |
|
| In a few places the lodes were so argentiferous that they supported operations which were primarily silver producing, with little associated lead output. |
|
| After the initial flurry of fossicking the prospectors were confronted with the task of extracting the gold from lodes. |
|
| Operating since the 1950s, the mines are the site of some of Argentina's best agate, amethyst, quartz and topaz lodes. |
|
| In the southern part of the moor, the cassiterite was usually found in relatively large grains, but the lodes were of very variable quality. |
|
| The mineralogy of the Copper lodes consists of chalcopyrite, pyrite, chalcocite, covellite and marcasite. |
|
| If you count yourself as one of that pack, though, this is the mother of all mother lodes you've been waiting for. |
|
| The mineral deposits are associated with multiple lodes and fractures that dip steeply and cut across both the granites and the country rocks. |
|
|
|
| The largest workable lodes are in Australia, Asia, and the United States. |
|
| Lodes of ore and inches of fertile loam have little bearing on a nation's prosperity and influence anymore. |
