  Description:
    Abstract:
      This study enhances existing thermal maturity maps of New
      York by establishing new subsurface conodont alteration
      index (CAI) data points from Ordovician and Devonian rocks
      as well as new %Ro and Rock Eval subsurface data points for
      Middle and Upper Devonian black shale units. This data is
      contoured into new thermal maturity maps of New York.
    Purpose:
      This data will allow better modeling of the burial,
      unroofing and hydrocarbon generation history for the
      Appalachian basin in New York, and is part of a larger,
      ongoing project which will include data from several
      adjoining states.

DATA_QUALITY_INFORMATION

  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      All attributes created during the creation process were
      displayed to the screen and checked against hard copies,
      but no formal tests were performed.
  Logical_Consistency_Report:
    These data are believed to be logically consistent, though
    no tests were performed. Line and point geometry is
    topologically clean.
  Completeness_Report:
    All of the new data generated for this report are located
    within the state of New York. Some peripheral points from
    previous studies were included for completeness and to
    compliment contouring. Several of these points are located
    in Canada.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        Positions of new data generated for this report were
        plotted using tabular position data supplied by the New
        York Geological Survey. These consisted of x-y coordinate
        pairs in degrees, minutes and seconds or in decimal degrees
        taken to 5 decimal places. The true accuracy of the
        original data is not known, but most of the data points
        should be located within a second of their true locations. It
        is possible that some well locations were previously rounded
        to the nearest minute. All locations were checked against a
        state map to make certain they plotted within the
        correct Township. The state map and county outlines supplied
        in this report were copied from the ESRI data set supplied
        with ArcView 3.1. This data is appropriate for use at State
        and inter-county scales, but may not be appropriate at
        intra-county scales.
    Vertical_Positional_Accuracy:
      Vertical_Positional_Accuracy_Report:
        No vertically attributed features were generated for this
        report, so no vertical accuracy estimates are made.

    Process_Step:
      Process_Description:
        Datapoints (well locations) were generated in ESRI ArcInfo
        from x,y coordinates provided by the New York Geological
        Survey . These points were plotted on a New York State, and
        counties outlines obtained from the ESRI ArcView 3.1 map
        dataset. Points from the Harris, Harris, and Epstein (1978)
        maps were incorporated by scanning the published paper maps,
        georegistering them to the New York State map in ArcInfo,
        and manually placing and attributing the sample locations
        in ArcInfo. CAI and %Ro isograds were interpreted from the
        point data and manually drawn over that data in ArcView 3.2.
