Name:
Named in 1843 by William Williams Mather, John Finch, and William Horton in honor of DeWitt Clinton [March 2, 1769 Little Britain, New York, USA - February 11, 1828 Albany, New York, USA], multi-talented American statesman and naturalist. Clinton was a Congressional senator for New York and later mayor of New York City. He was an organizer of the Historical Society of New York and the American Academy of Fine Arts. Clinton was one of the original surveyors of the route of the Erie Canal and later governor of New York state (July 1, 1817 - December 31, 1822. Work of the Erie Canal began with Clinton's breaking the ground for construction on July 4, 1817. Daniel Walker Howe (2007) wrote about Clinton: "The infrastructure he worked to create would transform American life, enhancing economic opportunity, political participation, and intellectual awareness." Sixteen towns and eight USA state counties are named for him.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
