... localities in the First Watchung Mountain basalt would naturally be expected. About 1908 a block 2x1x1 feet in size, and probably weighing originally over 100 pounds, was discovered in the Francisco Quarry at Great Notch. For some time this stood in front of the office, and the superintendent of the quarry...

... mineral to have been glauberite, Na 2 Ca(SO 4 ) 2 . Similar pseudomorphs in shale from Princeton, and cavities in the zeolite deposits of the First Watchung Mountain, in New Jersey, are believed to represent the same mineral. A preliminary announcement of these conclusions has already been made, 2...

.... It proved to be essentially identical with the hitherto imperfectly known stevensite , the nature of which is discussed in this article. The quarry lies some 16 miles southwest from the better known mineral localities around Paterson, but is in the same rock, the basalt of First Watchung Mountain. The rook...

... Field observations of Early Jurassic Watchung Basalt throughout the Watchung syncline, including 17 large trap-rock quarries, provide new data on the number of flows, their structure, and the eruptive style of the lavas. Three Orange Mountain Basalt flows, five Preakness Basalt flows, and two...

... cut into the relatively soft mudstones. Stratigraphically from bottom to top, the three ridges are known as the First, Second, and Third Watchung Mountains and average 183, 229, and 91 m thick, respectively (Faust, 1975). A fourth basalt ridge located west of the Third Watchung was recognized by Black...
