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.
Continental slope
You could tell an older rock from a younger rock by looking at it because the older rock isochron would have a steeper slope.
Slope
Continental Slope
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.
The slope is the steep incline at the edge of the continental shelf that descends into the ocean depths. The continental shelf is a gently sloping, submerged portion of a continent that extends from the shoreline to the shelf break where the slope begins.
