Published: 01 April 1973
AAPG Bulletin (1973) 57 (4): 809.
...John N. Truex ABSTRACT Isopach maps of the major zones of the East Wilmington field shed significant light on the structural evolution of the Wilmington anticline. A minor ancestral basement high marked the location of the Wilmington anticline at the close of the early Mohnian, but the structure...

...John N. Truex ABSTRACT The structural evolution of the Wilmington anticline in the Los Angeles basin, California, began with middle Miocene folding which probably was not coincident with the present anticlinal axis. The ancestral fold was truncated prior to the start of late Miocene deposition...

... Nardin and Henyey (1978) , while jumping aboard the “global tectonics” bandwagon, have overlooked my paper, “Structural Evolution of Wilmington, California, Anticline” ( Truex, 1974 ), perhaps the best documented and detailed case history of a limited part of their area of study. They are guilty also...
