Ann: Increase in Lockyer Deep Potential Resource Area, page-72

Thankyou oldgeo.
My science calculations have always been in degrees Kelvin and metrics so using Imperial units has meant using google to get conversion factors.
Forunately I was able to get the same figures as you for the base units but I am very rusty as I haven't used this stuff for 45 years.
Again thankyou for your patience and for doing the calculations.
We are very lucky on this thread to have people such as you and others who post great information.
