| 11. | Researchers in December 2016 announced the discovery of the element boron by " Curiosity " in mineral veins.
|
| 12. | These rocks were subsequently subject to hydrothermal alteration by and rich which in multiple stages formed the mineral veins.
|
| 13. | It consists largely of mineral veins yielding arsenic, barium, copper and lead which have been worked in the past.
|
| 14. | Later he issued an authoritative 2-volume work on mineral veins, " Untersuchungen �ber Erzg�nge " ( 1882 1885 ).
|
| 15. | The presence in the high part of the valley of mineral veins promoted since the antiquity an important mining activity.
|
| 16. | Regional uplift brought the deep-seated granite to the surface, where erosion exposed the rocks and the mineral veins they contained.
|
| 17. | There is evidence of historic mining activity in two locations on Great Dodd in efforts to exploit such mineral veins.
|
| 18. | As the granite cooled, it cracked, and hot solutions filled the cracks and formed mineral veins bearing gold and other metals.
|
| 19. | It was operated by a succession of different owners, driving five levels through mostly barren rock to explore three mineral veins.
|
| 20. | As the granite cooled, it cracked, and hot solutions infiltrated the cracks to form mineral veins bearing gold and other metals.
