yes its siderite , the three others are clay minerals (sheet silicates) while siderite is an iron carbonate (FeCO3).

yep, siderite. The other 3 are clays - montmorillonite and smectite in smectite group and illite in the illite group. Siderite is simply iron carbonate and occurs in large crystals to masses.

I would say smectite because it is a clay mineral but mineralogy was a long time ago.
Go to http://www.webmineral.com and look up the formulas.
