investigating the Eucla Basin Use the table below for your answers. 1.make a list of all the codes of the rock units found in your province. 2.use the legend to discover what rock types the codes represent. 3.determine what classification the rocks belong to (i.e. sedimentary, volcanic, intrusive, metamorphic). Eucla Basin ROCK CODE ROCK NAME ROCK CLASSIFICATION AGE (approx.) 1.What is the oldest unit in your province (Eucla Basin) (in Ma)? 2.What is the youngest unit in your province (Eucla Basin) (in Ma)? 3.Which geological time zone do most of the rock units belong to? (e.g., Cainozoic, Mesozoic, Palaeozoic, Proterozoic (Paleo-, Meso-, Neo-), Archean). 4.Do you have units Czv, Czc or Qm in your province? what are they? Do these units belong to your province or are they recent units that have been deposited on top of your province? (NOTE: "deposits" means that they are unconsolidated sediments that have not yet been lithified; "eolian" means wind-blown sediments; "alluvial" means river sediments; "lacustrine" means lake sediments). 5. Are there other rock units in the map area of the province that you feel do not actually belong to your province based on the rock type and age? This may be because they predominantly belong to an adjoining province and are only found at the edges of your province, or are only a minor or unusual occurrence. 6.Now that you have eliminated unwanted units, what is the predominant age range of your province? 7. Is there a dominant trend of structures (faults and folds) in your province that distinguishes it from other provinces (i.e. a predominant geographical orientation)? Is the trend consistent or does it change direction from one part of the province to another? In areas of strong deformation rock units are squashed, numerous folds and faults may result. Faults break the units up into thin slivers, folds bend the rock units into elongate blobs. In areas of very low deformation the faults and folds do not affect the rocks much and sedimentary rock units may cover vast areas with little or no change. 8. Is your province strongly or weakly deformed? Why do you say this?
