For what it’s worth Chat-gpt thinks it’s most likely spodumene in the cores.


Speculation About the Mineral in the Core:Based on the image and context, we cannot confirm with certainty whether the core contains lepidolite or spodumenewithout additional mineralogical data. However, here are some observations that might guide an educated guess:

Color and Texture:The darker sections in the upper rows of the core could suggest a dense, fine-grained rock, which may not clearly resemble spodumene (commonly found as pale, glassy crystals) or lepidolite (typically lavender to pinkish with a flaky, micaceous texture).The lighter sections in the lower rows appear more fractured or veined, which might align with the presence of spodumene if these areas contain coarse crystalline features.

Lithium Content (Li₂O):

The label mentions 2.1% Li₂O, which could correspond to either lepidolite or spodumene, as both are lithium-bearing minerals. However, spodumene often contributes to higher-grade deposits, especially in pegmatite systems.Context:Lepidolite is typically associated with micaceous, flaky textures and a distinctive purple or pink color, which does not seem obvious in this core.Spodumene tends to occur in granular or crystalline forms within pegmatites, often appearing in white, gray, or pale green hues, which could match some of the lighter, veined sections.

Conclusion:While the presence of spodumene seems more likely based on the geological context (hard-rock lithium deposits in pegmatites) and the lack of visually clear mica-like textures, confirmation would require mineralogical or chemical analysis, such as XRD or thin-section petrography.
