I do not have the complete knowledge of the properties and characteristics of the specific Antique Red Marble that you are referring to. However, in general, marble is not recommended for very dusty climates due to its soft and porous nature, which can make it vulnerable to erosion and staining. If the Antique Red Marble has been specially treated or sealed for exterior use, it may be able to withstand the dusty climate. It is recommended to consult with a qualified stone specialist or supplier to determine the suitability of this marble for your specific application.
