Expert Response

You have a great collection of rock and mineral samples.  To identify samples, it helps geologists to know where samples were found.  In looking at the linked geology map, all three of these are likely finds in Ward County.  The reddish rock and the gray rock are sedimentary, most likely sandy shale.  The yellow translucent rock is agate, a variety of quartz.  The attached links show the types of rock, ages and mapped units for Ward county and the geology of Texas.  Thank you for sharing!
