Answers to Questions For First Two Field Trips Geology 364 - Stratigraphy and Basin Analysis Dept. of Geology and Environmental Studies James Madison University Lynn S. Fichter      These answers are for both field trips, but are sorted out by field trip. Identify formations that are red in color.    First Field Trip      None    Second Field Trip      Rose Hill      Juniata      Hampshire Identify formations that are composed or quartz arenite.    First Field Trip      Antietam      Massanutten    Second Field Trip      Oswego      Tuscarora      Keefer Identify formations that have Bouma Sequences.    First Field Trip      Weverton      Martinsburg    Second Field Trip      Brallier      Mahantango Identify formations that have Hummocky Sequences.    First Field Trip      None    Second Field Trip      Reedsville    Although observe that the Lincolnshire is a shelf environment but does not show hummocky sequences.          And although we did not see it (yet!) the Foreknobs has the best examples. Identify formations that have Point Bar Sequences.    First Field Trip      None    Second Field Trip      Hampshire               Identify formations that have L-Bar/T-Bar Sequences.    First Field Trip      Massanutten    Second Field Trip      None    Oswego ? The Oswego is a strange formation; it may represent a fluvial system, and may be braided.

Identify formations that have Tidal Features.

First Field Trip      Beekmantown      New Market

Second Field Trip      Conococheague       Tonoloway

Identify formations that have Anoxic, and possibly deep water, features.

First Field Trip      Edinburg

Second Field Trip      Needmore

Identify formations that are Uniquely Different for some reason.

First Field Trip      Massanutten: braided river with quartz arenite

Second Field Trip      Oswego: My, my, don't we wish we knew how this was deposited.       Tonoloway: typical tidal features, but much smaller scale than other formations; and although we did not see it here; salt casts.       Mahantango: very proximal, amalgamated Bouma sequences

Arrange formations in Stratigraphic Order.

First Field Trip      Needmore      Massanutten      Martinsburg      Edinburg      Lincolnshire      New Market      Beekmantown      Antietam      Weverton Now try to combine the lists in stratigraphic order: Check Stratigraphic Column for answer.
