XXIX.—Petrography of Igneous Rocks from the Vatnajökull Region, Iceland, collected by Mr F. W. Anderson

In the following paper ninety-eight rocks collected by Mr F. W. Anderson from the Tertiary lavas and intrusions on the south-eastern margin of the Vatnajökull, and from the Pleistocene and Recent lavas, tuffs and sediments of Kverkfjöll Eystri on the northern margin of the ice-sheet, are described....

Description
Summary:In the following paper ninety-eight rocks collected by Mr F. W. Anderson from the Tertiary lavas and intrusions on the south-eastern margin of the Vatnajökull, and from the Pleistocene and Recent lavas, tuffs and sediments of Kverkfjöll Eystri on the northern margin of the ice-sheet, are described. Interest in the geology of the Vatnajökull region has been revived by several recent expeditions. The existence of active volcanoes under the Vatnajökull, and the eruptions that occasionally break through the ice-sheet, offer unexampled opportunities for the investigation of the peculiar igneous and sedimentary products which are the results of the contest between ice and volcanism, and for the solution of the “Palagonite Problem”, with which several authors have recently dealt.
