  "abstract": "Lithium-rich granitic pegmatites supply approximately 50-60% of global Li production, yet the physicochemical mechanisms driving their exceptional Li enrichment remain contested. Here, we integrate cathodoluminescence (CL) imaging and LA-ICP-MS trace element mapping of quartz crystals from miarolitic cavities at the world-class Bailongshan Li deposit (Western Kunlun Orogenic Belt, NW China) to decipher crystallization dynamics during the magmatic-hydrothermal transition. We identify three growth zones composed of a serrated core (Q 1 ) and oscillatory rims (Q 2 /Q 3 ) recording up to ≥5 discrete fluid-pulse events, with Al and Li concentrations spanning two orders of magnitude and co-varying with CL brightness. We demonstrate that episodic fluid pressure drops transiently accelerate crystal growth and thin the chemical boundary layer at the crystal-fluid interface. We interpret this thinning as suppressing diffusive re-equilibration and enabling the kinetic incorporation of coupled Al-Li substitutions into quartz, whereas under steady-state pressure near-equilibrium partitioning inhibits Li uptake. Diffusion modeling supports systematically increasing growth rates from core to rim, consistent with progressive fluid exsolution. Crucially, we show that miarolitic quartz exhibiting ≥5 high-frequency Al-Li oscillation cycles is a robust indicator of rare-metal fertility and enhanced Li-transport capacity, providing an exploration criterion applicable across the world's major Li pegmatite provinces",
