SYMBOL EXPLANATION
Contact between map units - Accuracy of location ranges from well located to inferred; dotted where concealed. All offshore contacts are considered approximately located
Fault - Solid where accurately located; long dash where approximately located; short dash where inferred; dotted where concealed; queried where continuation, identity, or existence is uncertain. Where age was determined in offshore area, age symbol is shown astride fault and relative offset is shown by U on upthrown side and D on downthrown side (relative or apparent). Age of fault is indicated as follows:
cuts strata of Holocene age cuts strata of Pleistocene age
cuts strata of Quaternary age cuts strata of Pliocene age
cuts Miocene or older strata
Anticline - Solid where accurately located; long dash where approximately located; short dash where inferred; dotted where concealed. Plunge direction indicated by arrowhead on fold axis
Synclinal Fold - Solid where accurately located; long dash where approximately located; dotted where concealed. Plunge direction indicated by arrowhead on fold axis
