Project Information

Principal investigators:
Tania Martins, Christian Böhm

Partnered with:
Anton Chakhmouradian (University of Manitoba)

Location:
Cinder Lake, part of 6NTS 53L15

 

Project Description

Main objectives:

The main objective of this project is to investigate the heterogeneous alkaline igneous rocks from the southwestern part of Cinder Lake. High-resolution aeromagnetic data of the area outline the possible shape and size of the Cinder Lake intrusive complex with linear magnetic highs coinciding with exposures of syenitic pegmatite that appear to occupy the outer shell of a concentrically structured intrusive body.

Methodology:

• Re-examination of previously collected material and conduct field work for improvement of existent maps and sample;
• Extensive petrographic studies and characterization of the different syenite units and mineralogical studies;
• Trace element geochemistry and geochronology.
  

 

Benefits:

Better knowledge of the mineralogy, whole rock geochemistry and geochronology of the Cinder Lake syenite. Possible identification of ultramafic and carbonatitic units genetically associated with the alkaline syenitic rocks.
