Hi, my favourite mineral foundation is Mineral Matte by Bourjois. I absolutely adore this texture and how it looks when applied. You should try it, it's not caky and it is very resistant.
I really like Bare Minerals touch of foundation gel, I find it easy to use and looks quite 'natural' plus it has SPF in it. It's a bit pricey but I can make a tube last quite a few months.
