What is the facies concept?
Sedimentary facies reflect their depositional environment, each facies being a distinct kind of sediment for that area or environment. Since its inception in 1838, the facies concept has been extended to related geological concepts.
What is facies analysis used for?
5.2. 2 Seismic Facies Analysis. Seismic facies analysis is the description and geological interpretation of seismic reflectors between sequence boundaries (Sieck and Self, 1977). It includes the analysis of parameters such as the configuration, continuity, amplitude, phase, frequency, and interval velocity.
How many facies are there?
There are seven widely recognized metamorphic facies, ranging from the zeolite facies at low P and T to eclogite at very high P and T. Geologists determine a facies in the lab after examining many specimens under the microscope and doing bulk chemistry analyses.
What is facies stratigraphy?
A facies is a body of sedimentary rock with specified characteristics, which may include lithology (lithofacies), fossils (biofacies), and hydraulic properties (hydrofacies).
What is a facies in medicine?
In medical contexts, a facies is a distinctive facial expression or appearance associated with a specific medical condition. The term comes from Latin for “face”. As a fifth declension noun, facies can be both singular and plural.
How are facies formed?
Sedimentary facies are either terrigenous, resulting from the accumulation of particles eroded from older rocks and transported to the depositional site; biogenic, representing accumulations of whole or fragmented shells and other hard parts of organisms; or chemical, representing inorganic precipitation of material …
What is a facies code?
A designated litho- facies code comprises a cluster of letters that respectively constitute: the sediment composition or grain size (upper-case lettering), the internal sedimentary structure and optionally subordinate qualifying cri- teria, such as distinctive mineralogical components and the nature of the basal …
What is facies map?
Facies maps are made at an isochronous surface or within a coeval interval. We map reservoir system thickness (1) to compare the distribution of reservoir-system thickness and field location and (2) to identify or predict locations with thick reservoirs and trapping conditions that are undrilled.
What does mask like face mean?
Masklike face: An expressionless face with little or no sense of animation; a face that is more like a mask than a normal face. Masklike face is seen in a number of disorders, including Parkinson’s disease and myotonic dystrophy. Also known as masklike facies.
What is coarse facial features?
Coarse facies. Definitions. Absence of fine and sharp appearance of brows, nose, lips, mouth, and chin, usually because of rounded and heavy features or thickened skin with or without thickening of subcutaneous and bony tissues.
What are facies changes?
A lateral or vertical variation in the lithologic or paleontologic characteristics of contemporaneous sedimentary deposits. It is caused by, or reflects, a change in the depositional environment.
What is a facies change?
What are lithofacies?
1. n. [Geology] A mappable subdivision of a stratigraphic unit that can be distinguished by its facies or lithology—the texture, mineralogy, grain size, and the depositional environment that produced it.
What is geophysical mapping?
Geophysical maps provide insight into an area’s geology by illuminating features and subsurface characteristics not apparent from a geologic map alone. They are particularly useful in regions where there are limited bedrock outcrops to study.
What is Cogwheeling rigidity?
Cogwheel rigidity is one of the criteria for the diagnosis of idiopathic Parkinson disease and is often an early sign of the disease. 3. Clinically, it is characterized by muscular stiffness throughout the range of passive movement in both extension and flexion.
What do coarse features mean?
Definition. Absence of fine and sharp appearance of brows, nose, lips, mouth, and chin, usually because of rounded and heavy features or thickened skin with or without thickening of subcutaneous and bony tissues. [
How many types of MPS are there?
Seven distinct clinical types and numerous subtypes of the mucopolysaccharidoses have been identified. Although each mucopolysaccharidosis (MPS) differs clinically, most individuals experience a period of normal development followed by a decline in physical and/or mental function.
What is facies sequence?
A facies sequence is a series of facies that pass gradually from one into another. A sequence can have an abrupt or erosive boundary, or be bounded by a hiatus, as indicated by a rootlet bed, reworking, or early diagenesis. Clastic environments have two important types of sequences.
What is a facies map?
A map showing the distribution of different types of rock attributes or facies occurring within a designated geologic unit.
What is the meaning of physical therapy?
: therapy for the preservation, enhancement, or restoration of movement and physical function impaired or threatened by disease, injury, or disability that utilizes therapeutic exercise, physical modalities (such as massage and electrotherapy), assistive devices, and patient education and training — called also physiotherapy. —.
What is the proposed model for physical functioning assessment?
The proposed model is meant to guide assessment of a wide range of physical functioning tasks in middle-aged and older suburban and urban dwellers. This could include assessment of a group with diverse performance levels or of individuals with varying performance levels across time.
What is the ICF framework for physical therapy?
The framework not only addresses the key diagnostic questions but also identifies the roles of other health-care professionals such as social workers, occupational therapist, psychologist, nutritionist, physician, and surgeons in restoring function. Benefits of physical therapy diagnosis using ICF
What professional activities serve the purpose of physical therapy?
Other professional activities that serve the purpose of physical therapy are research, education, consultation, and administration. From American Physical Therapy Association (APTA): Physical therapy as a health profession, HOD P06-99-19-23, House of Delegates Standards, Policies, Positions, and Guidelines, Alexandria, Va, 2009, APTA.
