* Geological Diversity: Different provinces have different geological formations. Some areas are dominated by sedimentary rocks (where you'd find sand and gravel), while others have more igneous or metamorphic rocks.
* Specific Locations: Even within a province, deposits can be very localized. You'd need to know the specific geological history and landforms of a particular area to pinpoint likely locations.
To help me give you a better answer, please provide more information:
* What country are you interested in? Different countries have different geological maps and resources.
* Are you looking for specific uses of these materials? For example, are you interested in building materials or something else?
* Do you have a particular region in mind? Knowing a specific area would narrow down the possibilities.
Once you provide more details, I can give you a more accurate and helpful answer.
