Short summary
This study presents new methodology for combined in-situ analysis of Rb-Sr and K-Ca in K-rich micas and feldspars. Simultaneous analysis is especially beneficial for small grains and/or detrital minerals where sample material is limited. This technique has the potential for identifying decoupling between the isotope systems, to further understanding of cooling and alteration processes in micas and feldspars, and increase knowledge of element diffusivity in these minerals.

Short summary
Laser-based dating of rocks and minerals is invaluable in geoscience. This study significantly advances our ability to model and correct for a process called down-hole fractionation (DHF) that impacts the accuracy and uncertainty of dates. We develop an algorithm that quantitatively models DHF patterns but can be used on other geoscientific data. The implications are far-reaching: improved accuracy, reduced uncertainty, and easier comparisons between different samples and laboratories.

In this contribution, we demonstrate in situ monazite lutetium–hafnium dating and compare results with uranium–lead dating. We present data from monazite reference materials and complex samples to demonstrate the viability of this method. We show that in situ lutetium–hafnium dating of monazite can resolve multiple age populations and may find use in scenarios where the uranium–lead system has been compromised.

This paper describes migmatites and associated rocks in SW Finland that have been studied using the new in situ garnet and apatite Lu–Hf geochronology method. The metamorphic constraints and age presented in this paper enhance our understanding of the geological evolution in SW Finland. The results reveal detailed temporal constraints for the tectonic evolution that can be linked to major events in adjacent tectonic blocks in both Finland and Sweden during the Svecofennian orogeny.

In situ Lu–Hf geochronology of garnet is applied to date a Finnish lithium–caesium–tantalum (LCT) pegmatite from the Somero–Tammela pegmatite region. The age obtained was 1801 ± 53 Ma, which is consistent with zircon ages of 1815–1740 Ma obtained from the same pegmatite. We show the in situ Lu–Hf method is a fast way of obtaining reliable age dates from LCT pegmatites.

Short summary
Radiometric dating methods, involving laser ablation as the sample introduction, require robust calibrations to reference materials with similar ablation properties to the analysed samples. In the case of the rubidium–strontium dating method, calibrations are often conducted to nano powder with different ablation characteristics than the crystalline minerals. We describe the limitations of this approach and recommend an alternative calibration method involving natural minerals.

Short summary
Short summary
Advancements in technology have introduced new techniques to more quickly and cheaply date rocks with little sample preparation. A unique use of this method is to date shales and constrain when these rocks were first deposited. This approach can also time when such sequences were subsequently affected by heat or fluids after they were deposited. This is useful, as the formation of precious-metal-bearing systems or petroleum source rocks is commonly associated with such processes.

Short summary
The article demonstrates a new technique that can be used to determine the age of calcite crystallisation using the decay of 176Lu to 176Hf. The technique is novel because (a) Lu–Hf radiometric dating is rarely applied to calcite and (b) this is the first instance where analysis has been conducted by ablating the sample with a laser beam rather than bulk dissolution. By using laser ablation the original context of the sample is preserved.
