A Self Test

  How Much Do You Understand?

    The Stage I enlarged drawing contains evidence of all the events and processes occurring during the Wilson Cycle. The question is, can you reconstruct them? Can you go through the final cross section and identify specific rock types, or specific tectonic regimes, or specific tectonic stages in the Wilson Cycle?

    Try This Tectonic Recognition and Identification: Without going back to the labeled cross section, go to this lettered drawing where different parts of the cross section are identified by letters. Do one of two things with these locations, either:
»  Identify the stage of the Wilson cycle they formed in, or . . .
»  Identify what tectonic regime they represent; e.g. DCM, volcanic arc, axial rift. etc. (All the letters are hot and will take you to an answer)

    Try This Two (Too) Rock Identification and Interpretation: Can you identify the various rock types in the Stage I cross section? Go to this numbered drawing where different rock units are identified with a number.
»  Identify the rock type (igneous, sedimentary, metamorphic) and specific rock (e.g. greenschist, arkose, etc.) that would reasonably be found at each location.

»  Describe the processes by which each rock formed. If the rock is altered from a parent identify the parent.

»  Identify the tectonic regime and/or Wilson Cycle stage each rock formed in.
