replied that the soil of Florida, although not equally rich, afforded the best conditions for the moulding and casting of the Columbiad, consisting as it did of sand and argillaceous
Although the beaks and feet of birds are generally quite clean, I can show that earth sometimes adheres to them: in one instance I removed twenty-two grains of dry argillaceous
earth from one foot of a partridge, and in this earth there was a pebble quite as large as the seed of a vetch.
This change in the vegetation marks the commencement of the grand calcareo argillaceous
deposit, which forms the wide extent of the Pampas, and covers the granitic rocks of Banda Oriental.
In rainy season, the argillaceous
material, absorbs water and accelerate the mass movement.
Areas with interpreted high resistivities appear related to thicker sections of greywacke interbedded with the argillaceous
acuruensis, which is restricted to Bahia, Alagoas and Pernambuco (Irwin & Barneby, 1982), and found associated with areas of cerrado and caatinga on argillaceous
and very rocky soils.
It is argillaceous
stone and is special kind of clay which is rich in iron.
The bluff is calcareous rock, and a sandy and argillaceous
marl, with comparatively pure limestone.
It is formed of a combination of marl and Pliocene sands (Pannonian) that covers argillaceous
marl and Sarmatic sands containing sandstone, micro-conglomerates and volcanic tufa, which can be rarely seen on the slopes.

According to the ISRM suggested methods for the argillaceous
swelling rocks (1989, Madsen, 1999), samples have to be protected from frost and extreme heat at all times during sampling and transportation.
The lithologies of red beds are mainly sandstone, siltstone, silty mudstone, argillaceous
siltstone, shale, or claystone.
