Are you classifying limestone fossil as “bio-clastic” or just "biological"?

Because there is ambiguity about the classification of fossiliferous limestone, this question will not be asked.

Will there be questions on Bowen's reaction series?

Yes, the students should be able to answer questions about Bowen's reaction series.  For example:

  • Given a list of minerals, specify the order of the first to crystallize to the last.
  • What type of igneous rock crystallizes at a given temperature?
Should we study anthracite coal as sedimentary or metamorphic?

Anthracite coal should be classified as metamorphic.  It was previously classified by petrologists as sedimentary rock, but a few years back scientific community decided that it has undergone enough pressure to be considered metamorphic - albeit very low grade metamorphic.


May students put letters and numbers on the chart that corresponds with the rocks in their box?

Students may put any information on the 8 1/2" x 14" chart that they may bring into the event, including the index letter or number that is on a rock specimen.

However, because they will not be allowed to bring their own rock specimens into the competition, it is unclear what value that information might have.

The focus this year is on a specific class (e.g., sedimentary); to what extent should we focus our attention on this type of rock vs others?

It is very important to study all of the rock types as well as the minerals. The official specimen list in the rules has both rocks and minerals.  The additional focus rocks and minerals are a relatively small portion of the total.  This proportion of specimens is relatively representative of the degree of focus.
