Description: Below is a list of special bulletins published by the Pennsylvania Geological Survey between 1944 and 1965. The bulletins are folios (mostly 13.5 inches by 18 inches) pertaining to the state’s oil and gas industry, and include brief reports on stratigraphy. Most of the folios have 1:24,000-scale maps of oil and gas fields, and many have smaller scale geologic structure, isopach, or lithofacies maps. More detailed bibliographic information (including the types of maps and map scales) is given in the Survey’s list of publications, Pennsylvania Geological Publications.
