Okay, the user wants me to translate "red-beds" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without any explanations.
So, "red-beds" is in English. I need to translate it. The term "red-beds" could refer to geological formations, like red sedimentary rocks. In Thai, "red" is "แดง" and "beds" in this context might be "ชั้น" (layers). So "red-beds" might be "ชั้นหินแดง" or "ชั้นดินแดง". But I should confirm the correct geological term. Alternatively, it might be a proper noun, like a specific formation. If it's a proper noun, maybe it's kept as is, but the user probably wants a translation. I'll go with "ชั้นหินแดง" as the most likely translation. Make sure there's no explanation, just the translation.
