Extract

Eight years ago (in 1907) Mr. F. N. Ashcroft, who for many years has devoted much of his leisure to bringing together choice specimens of the species included in the zeolitic group of minerals, turned his attention to the specimens occurring in the cavities of the basalt of Co. Antrim. He was fortunate enough to secure the services of Mr. Robert Bell, of Belfast, ill his quest, and between them they have searched many of the quarries and other places likely to yield good specimens of these minerals. Some of the early specimens obtained through Mr. Bell, which, however, did not include any chabazite, were exhibited by Mr. Ashcroft at the anniversary meeting of the Society, on November 12, 1907.

page 282 note 2 According to the Home Office List of Quarries for 1918, published in 1914, this quarry is owned by the Giant's Causeway Columnar Basalt Co., Portrush. The basalt of the quarry, part of which is finely columnar in structure, belongs to the Upper, while that exposed in the cutting belongs to the Lower Basalt Series. At the base of the rock-face and again just above an old iron-mine adit, a few yards to the cast of the quarry~ a bed of lignite is visible.
