PROPOSED NORTH AMERICAN GEOLOGIC-MAP DATA MODEL

SCIENCE LANGUAGE TECHNICAL TEAM

Examples of Geologic-map Database Queries

13 December, 2001

This document archives hypothetical geologic-map database queries
developed by members of the Science Language Technical Team (SLTT) as of
30 November, 2001. The queries were developed in order to gain a feeling
for the kinds of science concepts and science language that are resident
in geologic-map databases and that might be queried by users of digital
geologic-map information. The queries are archived just as they were
submitted, with no modification (except for syntax).

What is the diagenetic / metamorphic history of this region?

What is the erosional history of this region?

How does the lithology vary in time?

What were the conditions of deposition?

What are the (tectonic) pressures and stresses?

Where are sand and gravel deposits out of floodplains?

Where are tills or lake deposits less than 15 feet thick?

Where does the Fox Hills Formation pinch out?

Where do sandstone aquifers come to the surface?

What are the geologic-map constraints on the ages of faults?

What does this area look like if we simplify the geology?

Can I simplify it in different ways?

Can I define my own simplification scheme?

What is the structural relief on the top of the lower Pleistocene?

Who measured that strike-and-dip?

Was the light any good when this measurement was made?

What facing indicator induced the geologist to put a ball on the end of
the strike line?

Does a ball on the end of the strike line mean a facing indicator was
observed and interpreted confidently?

How confident is the interpretation of facing direction at this site?

Was that contact seen on the outcrop, on an aerial photograph, or
inferred by somebody sitting at a desk?

What are alternate interpretations of this geology?

A prospective buyer wanted to know if my house is in liquefaction-prone
young alluvium or not. I just looked at the State geologic map with
Internet Explorer (or MapGuide, or \...) and zoomed in until I could see
that it is. This may queer the sale (and I think it is wrong!). If the
sale falls through because of this, who do I sue?

What does the map look like if I make all the Tertiary rocks different
shades of orange and brown?

What portion of the geologic mapping shown on this area was funded by my
agency?

What is the mineral potential of that area?

Are all mineral occurrences indicated? Or only a subset?

Have all the mines pits and shafts been indicated?

Are there any age dates available for any of the rocks in the area?

Are there any chemical analyses available for rocks from the area?

How detailed was the mapping compiled to produce the map?

Who did the geologic mapping, and when, using what set of aerial
photographs?

Are the geologic contacts interpreted from field observation,
aeromagnetic maps, drilling data, etc?

Where is the indicator alteration and mineralization suggestive of a
particular sort of mineralization (PCD, VMS, epithermal gold, etc.) ?

Do the map units represent original lithology (protolith), or are they
metamorphic rock units?

What written literature is available about the area?

What published geologic maps include the area?

Is there a surficial geologic map for the area?

What are the major terrane boundaries and structures in the area?

Display the metamorphic isograds

What is the distribution of potential outcrop of the bedrock units?

What is the sequence of intrusive events?

Which faults are the oldest?
