Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.
Embark on a voyage through time with swisstopo’s topographic maps and travel through almost 175 years of Swiss cartographical history, even as far back as the time before the Swiss Confederation was founded. When it comes to the sustainable management of our living space, historical maps and digital 3D models are just as important bases as geological, geophysical and geotechnical datasets.
The Geo Cover vector dataset depicts all of Switzerland on the basis of the ,000 maps sheets.
(For brevity's sake, hereafter I will refer to the parent isotope as ).
In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.
