Strontium isotope systematics used to decipher the origin
The aim of this work is to determine the Sr isotopic signature in deep groundwaters from a granite matrix in terms of water–rock interaction (WRI) and mixing processes in groundwaters to better understand the recent hydrogeological and hydrogeochemical conditions of the site, and to aid in the design of a conceptual groundwater flow model 2

Oxygen, hydrogen, and strontium isotope constraints on
Oxygen isotope data are very useful in determining the source rocks of granitic magmas, particularly when used in combination with Sr, Pb, and Nd isotope studies For example, unusually high δ 18 O values in magmas (δ 18 O> +8) require the involvement of some precursor parent material that at some time in the past resided on or near the Earth's surface, either as sedimentary rocks or as
