If the isochron slope is 0.0077, the age in millions of years when the first evidence of abundant fossils would be around 129 million years (1/0.0077). This calculation assumes a linear relationship between the isochron slope and time.
To calculate the age in million years, you would divide 0.002 by 1 million: 0.002 / 1,000,000 = 0.000000002. This value represents the age in million years based on the isochron slope.
The age in millions of years can be calculated using the formula: Age = Isochron Slope / Decay Constant. For a common isotope like uranium-238, the decay constant is approximately 1.55 x 10^-10 per year. Using the isochron slope of 0.0077, the calculation gives an age of roughly 49 million years (0.0077 / 1.55 x 10^-10 = 49,677,419 years).
In a geological isochron, SR stands for "slop ratio" and RB stands for "ratio of initial isotopes." SR represents the slope of the isochron line, which gives information about the age of the sample. RB refers to the initial isotopic composition of the sample, which helps in interpreting the geological history and processes.
You could tell an older rock from a younger rock by looking at it because the older rock isochron would have a steeper slope.

Continental Slope
Yes, the continental shelf does have a slope, although it is generally very gentle. The slope leads down to the continental slope, which is a steeper gradient that marks the transition to the deep ocean floor. The continental shelf typically extends from the coastline to the shelf break, where the slope begins. Overall, the slope of the continental shelf is crucial for marine ecosystems and resource distribution.
It is part of a continental plate that is submerged by the ocean. At the edge of the continental shelf, the slope suddenly increases and begins to drop off, this is called the continental slope.
As m, in the equation y=mx+b, gets bigger the line begins to get steeper.
