"The Frenchman Mountains were formed nearly 2 billion years ago."
There are preCambrian basement rocks exposed, but the mountains themselves are Paleozoics not more than 540 million years old. More important, the limestones were thrust to the present position MUCH later -- perhaps less than 17 million years ago.
I heartily recommend the book "Geologic Tours in the Las Vegas Area" (Expanded edition) by the NV Bur. Mines and Geol., special pub 16 (2001, Mackay School of Mines). You will find this book in many local bookstores in the "local section", and it was sold at the RR visitor center at one time. Principal author is J.V.Tingley.
ISBN 1-888035-07-2
You shouldn't have to resort to the internet, but the book can be obtained... HERE
