These strata are also penetrated by granite veins, and Plutonic dikes, called “elvans.”[8] The granite of Cornwall is probably of the same date, and, therefore, as modern as the Carboniferous strata, if not newer.

Subsequently to these elvans, veins of copper and lead were produced, being of a date certainly posterior to the Silurian, and anterior to the Devonian; for they do not enter the latter, and, what is still more decisive, streaks or layers of derivative copper have been found near Wexford in the Devonian, not far from points where mines of copper are worked in the Silurian strata.

Later eruptions produced dykes of quartz-porphyry and other varieties, all locally called "elvans," which penetrate both the granite and the Killas.
