isochore

[′ī·sə‚kȯr]
(physics)
A graph that shows the variation of one quantity with another; for example, the variation of pressure with temperature, when the volume of the substance is held constant. Also known as isochor; isometric.

isochore

[′īs·ə‚kȯr]
(genetics)
In mammals and birds, an organizational unit of chromosome DNA that is usually characterized by a fairly constant proportion of guanine-cytosine base pairs throughout its length (usually 200-1000 kilobase pairs long); genes are concentrated in the G-C rich isochores.

The isochores for representative fluid inclusions, computed using Bakker's (1999) method, based on the adaptation of Bowers and Helgeson's (1983) equation of state, compared with the geothermobarometric data and mineral assemblages in the host rock, indicate lower pressure- temperature conditions for their trapping in accordance with the retrograde P-T evolution found in the MCT zone of Garhwal Himalaya (Sachan et al.
2) Fluid inclusion isochores imply a large variation in fluid pressure (i.
